The Three Pillars of Fitness

By Dr. Mercola
Exercise is like medicine and is sometimes best "taken as prescribed" to optimize your health.
Whether you're a beginner, intermediate or advanced, the workout "prescription" below covers the most important variables to keep in mind when creating and performing your fitness program and to help you reap maximum results.

Most every fitness program should include the following pillars at their base. These are the foundation that holds your program together:
  1. Peak Fitness High-Intensity Interval Training
    Exercising in shorter bursts with rest periods in between burns more fat than exercising less intensely for longer periods – and it's incredibly time efficient, as you can do it in a fraction of the time as compared to traditional cardio (an entire workout takes just 20 minutes, and only 4 minutes are at high intensity).
    Researchers believe this type of exercise works because it produces a unique metabolic response. Intermittent sprinting produces higher levels of chemical compounds called catecholamines, which stimulate more fat to be burned from under your skin and within your muscles. The resulting metabolic shift towards increased fat oxidation is thought to drive the increased weight loss.
    Further, high-intensity exercises like my Peak Fitness program engage a specific group of muscle fibers that you cannot engage through aerobic cardio, and engaging these muscle fibers causes a cascade of positive health benefits. These include improved fat burning and boosting your body's natural production of human growth hormone (HGH), which is a vital hormone that is key for physical strength, health and longevity.
    The key factor that makes interval training so effective is intensity. To reap maximum results, you need to work out at maximum intensity for short intervals, with rest periods in between these spurts of activity. You can get an idea of what that looks like by watching the videos on this page.
    Remember, to perform the Peak Fitness correctly, you'll want to raise your heart rate to your anaerobic threshold (220 minus your age), and to do that, you have to give it your all for those 30-second intervals.
  2. Active Isolated Stretching
    With Active Isolated Stretching or AIS, developed by Aaron Mattes, you hold each stretch for only two seconds, which works with your body's natural physiological makeup to improve circulation and increase the elasticity of muscle joints. This technique also stimulates your body to repair itself and prepare for daily activity.
  3. Strength Training
    Strength training is an integral part of a well-rounded exercise program, and it offers limitless benefits above and beyond muscle building, including weight loss, improved posture and improvements to back pain.
    Strength training can build bone density and reduce and even reverse loss of muscle mass as you age – and the more you strength train, the more muscle you will build, which will actually help you lose weight. A pound of muscle burns 10 times more calories than a pound of fat. Strength training can even help you reduce your risk of heart disease, as it helps you lose visceral fat, the most dangerous type of fat when it comes to cardiovascular health.

The Two Missing Factors in Fitness and Fat Loss

Before we get to the workouts, it's incredibly important to remember that optimal fitness cannot be achieved through exercise alone. There are two additional elements that are critical to both fitness and fat loss – without them you may be sabotaging your efforts.
  1. Nutrition: Your body needs a healthy diet not only for recovering from your workouts but also to provide the energy needed to perform them in the first place. And this means real energy, not an artificial boost from an energy drink or caffeine high. Your diet accounts for as much as 80 percent of the health benefits reaped from a healthy lifestyle. Much of your exercise will be in vain if you neglect your diet.
  2. Goals: Short-term, mid-range and long-term goals give you focus and motivation to help you keep moving full steam ahead on your fitness program. Set a deadline for yourself that's six weeks in the future. State that at this date, and at this time, you will "lose 4 inches off your waistline," etc. Take pictures in a swimsuit (from front, side and rear). Take another set in six weeks and compare your results. Once per week, take a measurement of your waist and your weight. Determine your emotional drivers – improving your blood pressure or boosting your self-confidence, for example – and remind yourself of these reasons often.

Take 4 Minutes and Warm Up Properly

The warm-up is a key component of your exercise program and can help you avoid injury – no matter what your fitness level. According to John Catanzaro, a Certified Kinesiologist and Certified Exercise Physiologist who operates a private gym in Richmond Hill, Ontario, one of the most common mistakes people do with their warm-up is to do aerobics prior to weight training.
A proper warm-up should raise your body temperature by one to two degrees Celsius (1.4-2.8 degrees Fahrenheit), and, it only takes 10-15 seconds of muscular contractions to raise your body temperature by 1ÂșC. So, instead of aerobics, which is non-specific in its target and takes much longer to perform, Catanzaro recommends the following warm-up routine before every workout.
1. Squat 9. Arms Horizontal
2. Split Squat 10. PNF Pattern
3. Toe Touches 11. Arm Circles
4. Waiter's Bow 12. Wrist Flexion/Extension
5. Side Bends 13. Wrist Circles
6. Trunk Twists 14. Shoulder Shrugs
7. Arms Vertical 15. Head Tilt
8. Arms Vertical Alternating 16. Head Rotation
Start slow and shallow and gradually increase speed and range with each repetition. All you need is 5-10 reps per movement. Doing too many repetitions during your warm-up will only increase lactate levels and decrease your strength and performance. Following this recommendation, you could be done with your warm-up in about four minutes.

Using the Super Slow Technique

Dr. Doug McGuff, M.D., an emergency room physician, is also an expert in high-intensity interval training who is a proponent of high-intensity interval training using weights. In the interview above, he discusses both high-intensity anaerobic-type training, and high-intensity super-slow weight training, which can achieve many of the same results using weights instead of a recumbent bike or elliptical.
Essentially, by aggressively working your muscle to fatigue, you're stimulating the muscular adaptation that will improve the metabolic capability of the muscle and cause it to grow. Dr. McGuff recommends using four or five basic compound movements for your exercise set. These exercises can be done using either free weights or machines. The benefit of using a quality machine is that it will allow you to focus your mind on the effort, as opposed to the movement.
Dr. McGuff recommends the following five movements:
  1. Pull-down (or alternatively chin-up)
  2. Chest press
  3. Compound row (A pulling motion in the horizontal plane)
  4. Overhead press
  5. Leg press
Here's a summary of how to perform each exercise:
  1. Begin by lifting the weight as slowly and gradually as you can. The first inch should take about two seconds. Since you're depriving yourself of all the momentum of snatching the weight upward, it will be very difficult to complete the full movement in less than 7-10 seconds. (When pushing, stop about 10 to 15 degrees before your limb is fully straightened; smoothly reverse direction)
  2. Slowly lower the weight back down
  3. Repeat until exhaustion (once you reach exhaustion, don't try to heave or jerk the weight to get one last repetition in. Instead, just keep trying to produce the movement, even if it's not 'going' anywhere, for another five seconds or so. If you're using the appropriate amount of weight or resistance, you'll be able to perform four to eight repetitions)
Immediately switch to the next exercise for the next target muscle group, and repeat the first three steps done in this fashion. Your workout will take no more than 12 or 15 minutes. While this may sound ridiculously short, once you've tried it, you'll likely realize that it's really all you can muster.
This super-slow movement allows your muscle, at the microscopic level, to access the maximum number of cross-bridges between the protein filaments that produce movement in the muscle.

The Great Importance of Recovery

The idea that fatigue is an important regulatory function to maintain physical homeostasis makes the advice to make sure you fully recover between workouts even more important.
An important piece of information gleaned from Dr. McGuff is that as long as your intensity is high enough, you can cut back on the frequency of the exercise without diminishing the results. In fact, if the intensity is really high, the frequency may need to be reduced, in order to continue improving.
"For any interval increase in intensity, there has to be a very disproportionate decrease in frequency for it to continue to be productive," he explains.
For example, as a weak beginner, you can exercise three times a week and not put much stress on your system. But once your strength and endurance improves, each exercise session is placing an increasingly greater amount of stress on your body (as long as you keep pushing yourself to the max). At that point, you would be wise to reduce the frequency of your sessions to give your body enough time to recover in between.
According to Dr. McGuff, once you're fit, you don't need the frequent spurts of growth hormone production. At that point, recovery takes precedence as being more important, and your recovery period could be anywhere from three to seven days. In fact, he strongly recommends NOT exercising too frequently once you are in fit condition, in order to avoid over-taxing your adrenals.

Choosing Your Customized Workout Plan

It's time to pick the customized workout plan that best fits your needs. Remember, if you are just starting out or haven't worked out in a while the beginner plan is for you. If you have some recent exercise experience, you can go ahead and start with the intermediate plan. For those who have been working out consistently and are looking to increase the intensity – and results – the advanced plan should be your choice.
Everyone is different so remember to use these workouts as guides and don't be afraid to modify the workout or switch to a different level to fit your needs.
It's time to get started!

Nutrition Supplements May Not Improve Exercise Performance But Can Reduce Muscle Damage


 
dietary_supplementsA new study in The Journal of Strength and Conditioning Research suggests that drinking a carbohydrate and protein supplement prior to and during exercise does not improve exercise performance. However, subjects who consumed the supplement did experience significantly reduced muscle damage compared to control subjects.
The Journal of Strength and Conditioning Research study examined the effects of consuming a carbohydrate and protein supplement prior to, during, and following an intense resistance exercise workout. The results indicate that a carbohydrate and protein supplement can significantly reduce muscle damage during acute bouts of resistance exercise, potentially allowing athletes to participate in their next high-intensity exercise bout in a shorter period of time. This finding can also apply to novice lifters and other individuals who regularly engage in resistance training.
The study authors are careful to note that although the supplement did not appear to influence exercise performance, previous studies were based on exercise programs targeting one main group of muscles, while the exercise program in this study incorporated the entire body.

Cancer spread and food, a new study

Posted on by Stone Hearth News

More than 40 plant-based compounds can turn on genes that slow the spread of cancer, according to a first-of-its-kind study by a Washington State University researcher.
Gary Meadows, WSU professor and associate dean for graduate education and scholarship in the College of Pharmacy, says he is encouraged by his findings because the spread of cancer is most often what makes the disease fatal. Moreover, says Meadows, diet, nutrients and plant-based chemicals appear to be opening many avenues of attack.
“We’re always looking for a magic bullet,” he says. “Well, there are lots of magic bullets out there in what we eat and associated with our lifestyle. We just need to take advantage of those. And they can work together.”
Meadows started the study, recently published online in the journal Cancer and Metastasis Reviews, with some simple logic: Most research focuses on the prevention of cancer or the treatment of the original cancer tumor, but it’s usually the cancer’s spread to nearby organs that kills you. So rather than attack the tumor, said Meadows, let’s control its spread, or metastasis.
He focused in particular on genes that suppress metastasis. As search engine terms go, it took him down many a wormhole in the PubMed research database, as the concept of nutrients and metastasis suppressor genes is rarely identified by journals. It’s even an afterthought of some of the researchers who find the genes.
“People for the most part did not set out in their research goals to study metastasis suppressor genes,” says Meadows. “It was just a gene that was among many other genes that they had looked at in their study.”
But Meadows took the studies and looked to see when metastasis suppressor genes were on or off, even if original authors didn’t make the connection. In the end, he documented dozens of substances affecting the metastasis suppressor genes of numerous cancers.
He saw substances like amino acids, vitamin D, ethanol, ginseng extract, the tomato carotenoid lycopene, the turmeric component curcumin, pomegranate juice, fish oil and others affecting gene expression in breast, colorectal, prostate, skin, lung and other cancers.
Typically, the substances acted epigenetically, which is to say they turned metastasis suppressor genes on or off.
“So these epigenetic mechanisms are influenced by what you eat,” he says. “That may also be related to how the metastasis suppressor genes are being regulated. That’s a very new area of research that has largely not been very well explored in terms of diet and nutrition.” Meadows says his study reinforces two concepts.
For one, he has a greater appreciation of the role of natural compounds in helping our bodies slow or stop the spread of cancer. The number of studies connecting nutrients and metastasis suppressor genes by accident suggests a need for more deliberate research into the genes.
“And many of these effects have not been followed up on,” he says. “There’s likely to be more compounds out there, more constituents, that people haven’t even evaluated yet.”
Meadows also sees these studies playing an important role in the shift from preventing cancer to living with it and keeping it from spreading.
“We’ve kind of focused on the cancer for a long time,” he says. “More recently we’ve started to focus on the cancer in its environment. And the environment, your whole body as an environment, is really important in whether or not that cancer will spread.”

Eating Quickly Can Cause Weight Gain


   
obama_eating_quicklyEating a meal quickly, as compared to slowly, curtails the release of hormones in the gut that induce feelings of being full. The decreased release of hunger hormones, can often lead to overeating according to a new study accepted for publication in January 2010 edition of the Journal of Clinical Endocrinology & Metabolism (JCEM),
"Most of us have heard that eating fast can lead to food overconsumption and obesity, and in fact some observational studies have supported this notion," said Alexander Kokkinos, MD, PhD, of Laiko General Hospital in Athens Greece and lead author of the study. "Our study provides a possible explanation for the relationship between speed eating and overeating by showing that the rate at which someone eats may impact the release of gut hormones that signal the brain to stop eating."
In the last few years, research regarding gut hormones, such as peptide YY (PYY) and glucagon-like peptide (GLP-1), has shown that their release after a meal acts on the brain and induces satiety and meal termination. Until now, concentrations of appetite-regulating hormones have not been examined in the context of different rates of eating.
In this study, subjects consumed the same test meal, 300ml of ice-cream, at different rates. Researchers took blood samples for the measurement of glucose, insulin, gut hormones and plasma lipids before the meal and at 30 minute intervals after the beginning of eating, until the end of the session, 210 minutes later. Researchers found that subjects who at the slowest had higher concentrations of PYY and GLP-1 and also tended to have a higher fullness rating.
"Our findings give some insight into an aspect of modern-day food overconsumption, namely the fact that many people, pressed by demanding working and living conditions, eat faster and in greater amounts than in the past," said Kokkinos. "The warning we were given as children that ‘wolfing down your food will make you fat,' may in fact have a physiological explanation."

Get in Shape Quickly, With these Advanced Weight Training Techniques


Written by Jeff Behar, MS, MBA   
Bodybuilding is the process of maximizing muscle hypertrophy through the combination of weight training, sufficient caloric intake, and rest.  One important factor of this "bodybuilding triangle": weight training is not as simple as it seems. To make the best gains in the shortest amount of time, it is important to understand a basic principle: intensity.

In terms of Bodybuilding, What Exactly is Intensity? Intensity is a feel factor. It is a way of lifting to put out a maximum effort.

Many people think they're training intensely, but the sad fact is most people are not. Most people "undertrain" and "overtrain" at the same time. What I mean by this is that they do not train intensely (which I will describe in greater detail later) while at the same time they train too long in the gym without the pump, which actually limits or even impedes their desired results.
Intensity: The Most Important Factor In Bodybuilding
Two guys can do the same exact fitness routine with the exercises, number of sets, and number of reps, yet have two different outcomes. Intensity is what determines success when it comes to maximizing your gains.

Three Basic Principles of Intensity
You can increase your intensity by 4 ways:
  • Increase the number of reps
  • Decrease the rest periods
  • Increase the amount of weight you lift
  • Increase the volume of work (sets)
Under each basic principle there are different approaches that can be employed. Understanding this will help you reach your goals quicker.  It will also help you break through "plateaus" (performance stagnation).  

Intensity Building Techniques
Increase The Number of Reps
The first way to add intensity in my opinion should be addition of reps. The best way is the X + 3 rule. In this rule you add intensity by adding 1, then 2 and then 3 reps beyond your target rep zone. When you can perform 3 reps more than the target zone you need to add weights. 5 lbs additional plates for major muscle groups and 2.5 lbs for minor muscle groups.

Adding more reps creates my hypertrophy in the muscle which is what is required for growth. This is another alternative way to intensify your workout. This can be accomplished in a simple approach, such as trying to get 10 reps vs. 8, or it can be done using advanced techniques such as:

Forced Reps
Forced reps training is an advanced training method, which is employed at the end of an exercise when you are unable to lift the weight on your own. At this point a training partner gives a small extra push while providing a spot so that you can overload the muscle by getting reps that you could not get on your own if you did not have the extra help, and a spot.

The moral support and encouragement alone often works and allows the bodybuilder to seek out a few more reps before the force reps are even employed. Typically this method is used for 2-3 extra reps, resulting in maximum overload and a great pump. Care should be taken however, because this is the most popular and consequently the most abused intensity technique.  People get hurt, people use it too often and overtrain, people use it with bad form and technique: all recipes for disaster.

Burns
Burns is another advanced technique similar to forced repetitions. With this method, you would use a sub-maximal weight that is so light that you could still use it to continue to pump and work the muscle after lactic acid has built up. When you keep working under these conditions, you get a great pump, and a huge burn from the lactic acid build up.

For those of you that may be curious, lactic acid is caused in part, to constant muscle contraction. It is created when the muscle burns sugars (in whatever form). Normally lactic acid gets squeezed out by normal muscle movement and lymphatic fluid, into the lymphatic ducts, where it is processed and eliminated from the body. What stops this is constant muscular tension (such as supersets, giant sets, forced reps).

Lactic Acid
During power-intensive exercises such as sprinting, when the rate of demand for energy is high, lactate is produced faster than the ability of the tissues to remove it and lactate concentration begins to rise. Lactic acid eventually will cause the muscle to tighten and bunch up, and constricts the flow of the lymphatic fluid. Since this cannot help wash out the lactic acid, it sits there, causing that familiar burning sensation. Probably more than you needed to know, right?

Forced Negatives
This technique focuses on the negative portion of muscle contraction (the eccentric or lowering phase). This principle involves the use of a spotter. To accomplish this technique you would choose a heavier weight and your partner would help you lift the weight and you would slowly control the weight during the downward movement.

For instance if you normally would use 225 pounds for 8 reps on a bench press, you would instead use 350 pounds and slowly lower the weight after receiving help lifting it off. Your partner would also assist you with during the upward pressing movement by pulling the weight off your chest while you are pressing the weight up.

Another way to accomplish this is using the same 225 pounds that you would normally use, but your partner would press down on the weight as it goes down for increased resistance, while you tried to resist the weight (slow the weight from approaching your chest). It is important that when using this advanced technique that the external force applied is done in a smooth and careful manner to avoid injury.

The Cheat Method
The Cheat Method is an advanced training technique that is utilized when one can no longer perform a repetition in strict form. It is used after performing a number of reps with good form until muscle fatigue begins to set in (or the weight is too heavy). At the end of a set, when you can't do any more reps with good form, use a bit of body swing or momentum to help get the weight past the sticking point, e.g. swinging the weight up a little at the start of a barbell curl.

By employing this technique you will use surrounding muscle groups to assist in the movement to complete additional reps to complete the set. An example of this technique would be as follows: when doing dumbbell chest presses, if you feel no longer you can do in perfect form, get the help of your shoulder and back (lat) muscles to assist lifting the weight.

It is key that when performing this technique you still let the major muscle targeted, to do most of the work. I always used cheat sets very sparingly as I was a stickler for good form, however there is a place in every bodybuilder's arsenal to use this technique occasionally.

Decrease The Rest Between Sets
There are also many techniques available for decreasing the rest between sets. They may include the following:

Drop Sets
Drop Sets, AKA Descending Sets, is the most basic and yet one of the best techniques to maximize intensity. You begin by reaching failure with a weight, as soon as you hit failure, lessen the weight, and then continue the set until failure is reached again.

Lets say you were to perform triceps pulldowns with a 90-pound stack. If you reached failure at 12 reps, you would strip the weight down to 70 pounds and continue. A single drop or descending set is when you lower the weight once. A double drop or descending set is when you lower the weight twice (for instance from 90 - 70, then from 70 - 50 pounds).

My favorite exercise is to do a 6 set drop set while doing dumbbell curls running the stack and doing each set to failure. I might start with 50 pound curls, then drop to 40 and perform the reps to failure, then immediately pick up the 30 pound dumbbells to failure, then proceed to do reps with the 25 pound dumbbells until, failure and then finish off with 20 pound curls till failure... then work in a few cheat reps! By employing this technique I get 18 sets of arm curls done in about 12 minutes and am done!

Strip Sets
Strip sets are essentially drop sets. If we want to be technical, it refers to "stripping" weight from a bar reducing the weight that you're using by 10% or so with each succeeding set (where as a drop set can be done on a machine, using dumbbells, etc.). For example, if you start out with 100 pounds for curls, then on your next set you would do 90 pounds and 80 pounds on your subsequent set.

These are done with barbells. Do a set then, without racking the bar, get two spotters to pull off a preset amount of weight. Continue with that weight. Keep stripping as desired. This will thoroughly burn out a muscle.

Supersets
A Superset is a technique where two or more exercises are performed back to back. When three exercises are performed in succession it is referred two as a triset superset. This is another good way to train if time is limited.  Supersetting involves doing two exercises with no rest in between.

Supersets can be in two ways. One way is doing two different exercises - for bodybuilding routines - in a row that hit the same muscles. Other way is doing two exercises - for bodybuilding routines - in a row hitting two different muscle groups. Supersets work best when targeting opposing muscle groups. Performing them this way allows for a better pump, as well as more reps.

Multi-Exercising
Multi-exercising is often incorrectly referred to as supersets. Multi-exercise sets are different than supersets. Multi-exercise sets use different exercises for each set instead of just doing one exercise for all sets.

With this type of training, you will be able to hit a particular muscle in different angles. For example, instead of doing 4 to 6 sets of a particular exercise for a body part, you would instead do different exercises for each set each time.  For instance for a chest press - instead of 6 sets of flat bench you do one set of barbell flat bench press, then a set of incline dumbbell presses, followed by a set of dips, decline flyes and finally cable crossovers. Unlike supersets, you would have rest periods between sets to enable you to approach each set heavier.

Giant Sets
A giant set is the practice of going from one exercise to another very quickly. One of the risks with this technique is that the muscle is fatigued so quickly that there is a tremendous loss of efficiency and benefit. However, by moving from one set to the next relatively quickly you can keep the heart rate elevated, and it is a good muscle confusion technique when employed periodically. Giant sets, in my opinion, are also good for conditioning. They should not however the cornerstone of your training methods since this type of training when I have little time to train, and I need to get a quick workout in.

Increase The Weight
Increasing the weight is not for the faint hearted. There are risks. Risks of improper form resulting in injuries. Probably most known for employing this principle was the late Mike Mentzer, who wrote many articles, and wrote books and developed audio tapes about what he coined his "Heavy Duty Training Principle".

His approach became extremely popular among bodybuilders especially after Mentzer won the 1978 IFBB Mr. Universe contest in which he was the first bodybuilder ever to receive a perfect 300 score from the judges.Mentzer's system was based on the principle of "intensity" as emphasized by Arthur Jones. So as not to overtrain, Mentzer's system was based on a limited amount of sets with adequate rest in between (4-8 days in between each workout).

Increase The Number Of Sets
Increasing the overall volume of work, by either increasing the number of sets per exercise or increasing the number of exercise per body part, which results in a greater number of overall sets as well, is also another way to increase intensity, especially if the overall work volume is completed in the same amount of time that less volume had been completed in, 

Other Advanced Techniques To Increase Training Intensity

Pre-Exhaust Method
This method is one of my favorites, so that I can reduce the weight a bit and reduce the stress on my joints while maintaining the force on the muscle.

The pre-exhaust method is typically done by performing an isolation movement first - like leg extensions - followed by a compound movement - such as the leg press, which works more than one joint. The principle is that on the second exercise, the muscle can be pushed into the range of failure very quickly by first employing the pre-exhaust method.

Partial Reps
Partial rep technique is simply moving the weight through a partial range of motion (usually, but not necessarily, the strongest range of motion of the exercise, e.g. the top 6 inches of the bench press). This allows much more weight to be used. The technique is often performed at the end of an exercise when you do not have the energy to complete full reps. Partial repetitions are good for eking out a little bit more out of the exercise. My favorite exercise is the squats. As I lift very heavy weights during squats I find it difficult after 4-5 reps, I then do partial reps thereby recruiting those muscle fibers, which are not yet fully tired.

Deep Reps
Deep reps are done to recruit additional muscle fibers. A simple illustration would be squatting slightly passed parallel, performing deep dips, or doing chair pushups for a deep stretch. It is important that proper care is employed, and proper warming up is done, so not to overstretch or tear a muscle.

Slow Negatives
Slow negatives is a technique that is slightly different from Static Training in that it is typically used at the end of a set when your muscles are failing but you want to get more out of the set in order to drive it into the critical "growth phase."

How it is performed is that you simply slow down the eccentric portion of the exercise (the eccentric portion of the exercise is the portion in which the muscle is lengthening under tension). To illustrate this point, if you were to do a slow negative with a barbell curl, you would slow the rep as you lower the bar towards your upper thigh; would constitute the negative or eccentric portion of the exercise.

A simple approach is to perform the eccentric movement taking 4 seconds, while taking 2 seconds during the concentric movement (in the case of a barbell curl the concentric movement would be the positive part of the exercise - the action of raising the bar towards your shoulders).

With this method, it is common to also employ the Cheat Principle during the concentric movement to maximize the amount of weight and number of reps that can be performed. This technique in my opinion is very effective and can be used at any time - even when training alone.

Static Training

Static training is an advanced training technique designed to generate high intensity by maximizing weight while minimizing hold times. How this is done is by holding on to the muscle's particular position for an extended amount of time (typically five to fifteen seconds) to give the muscle a new way of training and experience a different load.

This technique in my opinion is very effective because when used sparingly provides the muscle with a force not typically employed, and as such it can also employ the recruitment of additional supporting muscle fibers. It is also a favorite of mine because it can increase intensity on the muscle without having to add a lot of additional weight, which can pose strain on the joints. Another good benefit is that it can be used at any time - even when training alone.

Speed Varying
This technique involves changing the speed that you perform the reps, while maintaining proper form. Often utilizing quick explosive movements at the point of force. Then employing slower static training methods during the negative (downward) rep.

Important Points To Consider When Increasing Intensity
 
Approach this in a systematic way to avoid injuries. Weekend warriors typically get hurt and drop out before success. It is great to get inspired, but approach your increase in intensity is a smart way.

Stretch and properly warm up to reduce the chances of injury.
Stretching FOLLOWING an intense workout is just as, if not more important than stretching before the workout to reduce chances of injury, and to increase recovery.

Feed the Fire. Ensure that you get enough calories and proper nutrition, supplementing vitamins and minerals when needed. Failure to do so can result in overtraining, and as a minimum will limit your growth.

Ensure that you get enough rest. Your muscles don't grow when they are being worked; they grow only when they are at rest. If you give recovery time for the muscles, they will become bigger and stronger. Getting enough rest will also help prevent overtraining. If you are not giving time for recovery, the muscles remain the same and there will be no growth in the muscle.

Be aware of signs of overtraining. Symptoms of overtraining include lethargy (tiredness), aches, pains for extended periods of time, reduced strength, reduced stamina and reduced immunity. If you experience these symptoms, stop working out, take rest and start back with a new routine.

Hydrate. Water is also the most abundant nutrient in the body, not to mention the most important. It is the most critical nutrient for health, growth, and development. In order to move muscle, you need water. Muscle is considered an active tissue and water is found in the highest concentrations in active tissue. Although water does not provide energy in the same way carbohydrates and fat do, it plays a very important role in energy transformation. Water is the medium in which all energy reactions take place.  Therefore, you need to drink a lot of water for health, stamina, fuel, and building muscle.  Failure to hydrate will diminish your performance in the gym. It will result in decreased strength, decreased endurance, potential cramping and more.  Also of importance, most lethargy is caused by dehydration.  Instead of running for that red bull that will leave you crashed after the initial "high" try drinking enough water. You will be amazed at the difference in your overall energy levels. Remember, if you get thirsty, you are already in dehydration mode. Solution: drink at least 16 ounces before and immediately after your work out, and also try to drink water during as well. 

It’s also essential that you drink water for health and building muscle. Without it, muscle strength, control and stamina are all weakened which will reduce your ability to build muscle. Drinking water is important because it helps bring nutrients to the muscles and helps pass toxins from your body. Water also helps out with the lubrication of your joints. Water is an ingredient in the makeup of the synovial fluid, which is the lubricating fluid between your joints. If your weight lifting diet is lacking in water, even for a brief period, less fluid is available to protect these areas.
Remember, if you are employing the advanced lifting techniques discussed above by adding more weight, more reps, and more sets (and thus more stress to your body), the demands from weight lifting on the joints will increase. Adequate water intake is imperative to support the protective fluid needed for optimum performance and to maintain normal healthy joints.

Conclusion
When you increased the intensity of your workouts you will not only see better strength, tone, and muscle size gains, but you find yourself even more dedicated to your bodybuilding workout. Increase the intensity and  you will undoubtedly reap the rewards from your efforts.

It is important, however, to remember that high intensity workouts can result in central nervous system overload. Therefore in my opinion, high-intensity exercise is effective for workouts of short duration only.

With a long workout, high-intensity training results in overtraining and central nervous system burnout. One way to avoid this is to perform a high intensity workout for just one body part at a time, and if your training calls for two body parts to be trained, that the other body part be trained in a more traditional manner.

Employ the intensity principles in a smart and consistent manner, get the proper amounts of rest, and fuel your body correctly with the proper nutrients, supplements and water and you will be surprised how quickly your efforts will pay off!

Leg Raises -Leg raises place primary stress on the lower half of the rectus abdominis although the muscle fibers of the upper rectus abdominia are recruited as well. Secondary stress is also placed on the intercostal muscles.Because this movement works the hard to work lower abs you want to do this exercise before crunches. How to do: 1. Lie on your back on an inclined ab board with your head toward the raised end. 2. Grasp the end of upper bench with your hands to stabilize your body. 3. Bend your leg 15-20 degrees or until you feel your back relax. 4. Use your abdominal muscles to raise your feet in an arc to a position directly above your head. 5. Drop your feet in a return arc until they clear the bench. 6. Repeat until failure (get 15-25 reps).

Reverse Crunches - Reverse Crunches are a great exercise for working the lower abs. 1. Lie flat on your back with legs extended. Raise your legs into an L position with your abs. You can flex your knees a bit.2. Lower them to almost floor level and raise again.3. Keep going until failure.

Roll up Crunch - Targets: Rectus abdominis (the "six-pack" muscle). 30 percent more effective than the standard crunch because the move challenges your abs through a fuller range of motion, recruiting more muscle fibers. 1. Lie back with legs straight and arms extended above head next to ears. 2. Bring arms forward, tilt chin down, and slowly curl upper body up, reaching hands to toes. 3. Repeat 15- 25 times.

Bicycle Crunch - Targets: Upper Abdominals, Obliques, And Hip Flexors. 1. Lie back with legs straight and arms extended above head next to ears.2. Bring arms forward, tilt chin down, and slowly curl upper body up, reaching hands to toes. 3. Repeat to failure.

How To Build Solid Muscle

How is Muscle Built?

Building muscle is basically an adaption process which happens in the body. During a weight training session, your micro fibers within the muscles are torn due to the excessive strain which is being placed on the muscle while you lift the weight. This is the reason why you experience soreness the day after a weight training session. During the resting phase, your muscle fibers are repaired, built and become stronger with the aid of protein. This is why it is essential that you include protein in the diet for maximum muscle mass gains. Without protein, the muscles will not be able to repair themself and instead of growing, they may actually become smaller due to the muscle breaking itself down to extract protein in order to heal itself properly. Protein usually comes from animal type products but is also found in many other types of food. The best sources of protein which I personally recommend are fish, meat, eggs and whey.

The Adaption Process

After weight training for some months, you may find it difficult to become sore the next day after a weight training session. This is because the body gets used to the constant strain which it is always being placed under and therefore the fibers become more stubborn and harder to tear. It is important to vary your weight lifting routine in order to shock the body and create maximum muscle fiber tear. This can be achieved by giving your workouts some variety. Super sets are a great way to shock the body into growth by giving the muscles maximum fiber tear. A super set is when you perform a set, and then perform another set on a different exercise immediately after, with no rest in between. For example you may perform 10 reps of front lateral raises, followed by 10 sets of side lateral raises immediately after. You can also vary super sets for an even more intense workout by performing 3 or even 4 lots of super sets. Drop sets are similar to a super set but instead of immediately performing another exercise, you stay with the same exercise and drop the weight or increase it. For example you may start on 100 kilograms, perform 10 reps, move down to 80 kilograms, perform 10 reps and so on.

Building muscle requires serious dedication and motivation. If you lack either of these I am afraid muscle building may not work for you. Make sure that your diet is in check and you lift heavy and I assure you that you will be gaining solid muscle in no time!

Vitamin D Can Help or Hinder Your Weight Management

Vitamin D, once thought to influence little more than bone diseases such as rickets and osteoporosis, is now recognized as a major player in overall human health. Most recently, new studies suggest that your vitamin D status can even help or hinder your weight management, which I'll review below.
It's a tragedy that dermatologists and sunscreen manufacturers have done such a thorough job of scaring people out of the sun. Their widely dispersed message to avoid the sun as much as possible, combined with an overall cultural trend of spending more time indoors during work and leisure time has greatly contributed to the widespread vitamin D deficiency seen today.
Vitamin D is actually not a vitamin at all but a potent neuroregulatory steroidal hormone, shown to influence about 10 percent of all the genes in your body. We now know this is one of the primary reasons it can impact such a wide variety of diseases, including:
Cancer Hypertension Heart disease
Autism Obesity Rheumatoid arthritis
Diabetes 1 and 2 Multiple Sclerosis Crohn's disease
Flu Colds Tuberculosis
Septicemia Aging Psoriasis
Eczema Insomnia Hearing lossex
Muscle pain Cavities Periodontal disease
Athletic performance Macular degeneration Myopia
Pre eclampsia Seizures Fertility
Asthma Cystic fibrosis Migraines
Depression Alzheimer's disease Schizophrenia

Vitamin D Deficiency Contributes to Weight Gain in Older Women

A new study of more than 4,600 women age 65 and older shows that having low vitamin D levels can contribute to mild weight gain1. Previous research has already showed that obese individuals tend to have low vitamin D levels. Women who had insufficient levels of vitamin D gained about two pounds more compared to those with adequate blood levels of vitamin D during the 4.5-year long study. Those with insufficient levels also weighed more at the outset of the study.
According to Medicine.net2:
"The study can't say whether low vitamin D is causing the weight gain or just reflecting it."The study is the first step that we need to evaluate whether vitamin D might be contributing to weight gain," [lead researcher Erin] LeBlanc says. But there are some theoretical ways that low vitamin D could contribute to weight gain, she says. Fat cells do have vitamin D receptors. "Vitamin D could affect where fat cells shrink or get bigger."
Here, vitamin D levels above 30 nanograms per milliliter (ng/ml) were considered "sufficient." As I've previously reported, based on the latest vitamin D research this is still far below optimal, so it's difficult to say what the outcome might be if you were to actually optimize your levels by getting your blood level above 50 ng/ml. Still, despite this low "sufficient" level, 80 percent of the women in the study were found to have insufficient levels, meaning below 30 ng/ml. This gives you an idea of just how widespread this problem really is.

Vitamin D Deficiency Common among Adolescents Evaluated for Weight Loss Surgery

A second study found that more than half of obese adolescents seeking weight loss surgery are deficient in vitamin D. Eight percent were found to have severe deficiencies, and teens with the highest BMIs were the most likely to be vitamin D deficient. Less than 20 percent had adequate vitamin D levels. The research correlates with previous studies showing vitamin D deficiency in adults seeking bariatric surgery. (The results were presented at The Endocrine Society's 94th Annual Meeting in Houston on June 26.)
According to Science Daily3:
"This is particularly important prior to bariatric surgery where weight loss and decreased calcium and vitamin D absorption in some procedures may place these patients at further risk," said study lead author Marisa Censani, M.D., pediatric-endocrinology fellow at Columbia University Medical Center, in New York City.
... "These results support screening all morbidly obese adolescents for vitamin D deficiency, and treating those who are deficient, particularly prior to bariatric procedures that could place these patients at further risk," Censani said."
In the US, bariatric weight-loss surgery, such as gastric bypass surgery, is becoming increasingly common among all age groups, including children. Gastric-bypass surgery involves surgically removing a section of your stomach, which limits the amount of food it can hold. However, this procedure is fraught with risks, and maintaining proper nutrition post-surgery is a common challenge that can result in malabsorption syndromes. It's important to remember that vitamin D, as well as vitamin A, E, and K are fat-soluble, and need a certain amount of healthy fat to be absorbed properly.

What is the OPTIMAL Level of Vitamin D?

The ideal way to optimize your vitamin D levels is through adequate, safe sun exposure or using a safe tanning bed. However, whether you're tanning or using a vitamin D supplement, it's important to get your vitamin D levels tested to ensure you're within the optimal range of 50-70 ng/ml. For more information about proper sun exposure and how to determine whether you can actually get enough vitamin D from the sun at your location during different times of year, please see this previous article.As mentioned earlier, the "normal" 25-hydroxyvitamin D lab values are typically between 20-56 ng/ml. "Sufficient" levels are often considered to be around 30 ng/ml, as in the studies above.
However, this range is too broad to be ideal, and too low to support optimal health.
Beware that any level below 20 ng/ml is considered a serious deficiency state, increasing your risk of as many as 16 different cancers and autoimmune diseases like multiple sclerosis and rheumatoid arthritis. The OPTIMAL value that you're looking for is 50-70 ng/ml. Keeping your level in this range, and even erring toward the higher numbers in this range, is going to give you the most protective benefit.
But how do you get within that range?
While vitamin D experts typically recommend 35 IU's of vitamin D per pound of body weight, it's important to understand that there's no one dosage recommendation that will be applicable for everyone. The only way to determine how much vitamin D you really need is to get your levels tested at regular intervals to make sure you're staying within the optimal range of 50-70 ng/ml, and adjust your dosage accordingly. If you're supplementing, you may find that you don't need to supplement during the summer, if you're getting sufficient amounts of sun exposure, for example. But you won't know if you don't get your levels tested.

What is the OPTIMAL Way to Obtain Vitamin D?

There is simply no question in my mind that you were designed to receive your vitamin D from ultraviolet B exposure on your exposed skin and ideally this should come from the sun. For virtually the entire history of the human race this is how vitamin D was obtained.  Although vitamin D is in some animal foods it is in relatively low quantities and to my knowledge there are no known ancestral populations that thrived on oral vitamin D sources. Although we can absorb vitamin D orally because it is a fat soluble vitamin, there is strong emerging research that suggests this lacks many of the benefits of vitamin D.
The majority of the research documenting the benefits of optimized vitamin D levels was done with those that had not taken oral vitamin D but had increased their levels naturally through exposure to the sun. I personally have not taken any oral vitamin D for over two years and have been able to consistently keep my levels over 60 ng/ml.   This is partly related to the fact that I work in a sub-tropical environment in the winter.
If I could not do that there is no question that I would still not use oral vitamin D but would use a high quality safe tanning bed that used electronic ballasts that did not emit any dangerous EMF.

How to Know if You're Getting Vitamin D from Your Sun Exposure

The caveat here is that not all sun exposure will allow for vitamin D production. The key point to understand is that sunlight is composed of about 1500 wavelengths, but the only wavelength that makes your body produce vitamin D are UVB-rays, when they hit exposed skin. The UVB-rays from the sun must pass through the atmosphere and reach where you are on the earth in order for this to take place. This obviously does not occur in the winter for most of us, but the sun's rays are also impeded during a fair amount of the year for people living in temperate climates.
So how do you know if you have entered into the summer season and into the time of year, for your location, where enough UVB is actually able to penetrate the atmosphere to allow for vitamin D production in your skin?
Due to the physics and wavelength of UVB rays, they will only penetrate the atmosphere when the sun is above an angle of about 50° from the horizon. When the sun is lower than 50°, the ozone layer reflects the UVB-rays but let through the longer UVA-rays.
So the first step is to determine the latitude and longitude of your location. You can easily do this on Google Earth, or if you are in the U.S. you can use the TravelMath Latitude Longitude Calculator to find your latitude and longitude. Once you have obtained that you can go to the U.S. Navy site to calculate a table to determine the times and days of the year that the sun is above 50 degrees from the horizon. 
Translated to the date and time of some places on the globe, it means for example: In my hometown of Chicago, the UVB rays are not potentially present until March 25, and by September 16th it is not possible to produce any vitamin D from the sun in Chicago. Please understand it is only theoretically possible to get UVB rays during those times. If it happens to be cloudy or raining, the clouds will also block the UVB rays. For a more detailed understanding of this, please view the following video, and/or read through the corresponding article.

Even Easier if You Have Apple System

Alternatively, if you have an iPhone or iPad you can download a free app called D Minder, which will make all the calculations for you. It was made by an Apple developer who was motivated to simplify the process after he watched the video above.
From a health perspective it doesn't make much sense to expose your skin to the sun when it is lower than 50 degrees above the horizon because you will not receive any valuable UVB rays, but you will expose yourself to the more dangerous and potentially deadly UVA rays. UVA's have a longer wavelength than UVB and can more easily penetrate the ozone layer and other obstacles (like clouds and pollution) on their way from the sun to the earth. UVA is what radically increases your risk of skin cancer and photoaging of your skin. So while it will give you a tan, unless the companion UVB rays are available you're likely doing more harm than good and should probably stay out of the sun to protect your skin.
During the times of the year when UVB rays are not present where you live you essentially have two options: You can use a safe tanning bed or you can swallow oral vitamin D3.

Alternative to the Sun—A Safe Tanning Bed

During the summer months, you can generally get enough vitamin D from just spending some time outside every day. Under optimal environmental exposures your body can produce about 20,000 IU of vitamin D per day with full body exposure, about 5,000 IU with 50 percent of your body exposed, and as much as 1,000 IU with just 10 percent of your body exposed.
In the winter months however, and/or times of the year when insufficient amounts of UVB rays reach your location, you will most likely not get enough vitamin D. In that case, I recommend using a safe tanning bed, which is still better than oral vitamin D.
One of the caveats here is to make sure you're not being exposed to harmful EMF exposure. Most tanning equipment, and nearly all of the early beds from which these studies were conducted, use magnetic ballasts to generate light. These magnetic ballasts are well known sources of EMF fields that can contribute to cancer. If you hear a loud buzzing noise while in a tanning bed, it has a magnetic ballast system. I strongly recommend you avoid these types of beds and restrict your use of tanning beds to those that use electronic ballasts.

Warning: Newer Vitamin D Tests Often Inaccurate, Study Finds

Doctors are becoming increasingly aware of the importance of vitamin D,According to Medscape, vitamin D testing has increased six- to 10-fold over the last decade, and has become one of the most frequently ordered lab tests. However, it's important to know that there can be significant differences between available vitamin D tests, and according to a recent study, two newer tests appear to be inaccurate more than 40 percent of the time.
The findings are still preliminary and have not yet been peer-reviewed. The study was presented at the annual meeting of The Endocrine Society in Houston on June 23-264. According to Medscape.com5:
"Researchers say newer tests tend to overestimate the number of people who are deficient in vitamin D... The new tests, made by Abbott and Siemens, were approved by the FDA last fall. They're part of a wave of faster, less expensive tests designed to help laboratories keep up with a boom in demand for vitamin D testing... Holmes and his team wanted to see how well the new tests performed compared to an older, more expensive, and more time-consuming reference method... They ran blood samples from 163 patients on all three tests.
The Abbott Architect test was outside an acceptable margin of error -- meaning that the results were either 25% too high or too low, about 40% of the time.
The Siemens Centaur2 test was either too high or too low in 48% of samples.
... The new tests use blood proteins called antibodies that bind to vitamin D. They're faster because they look for vitamin D in samples of whole blood. In the older, reference method, vitamin D is separated from the blood and measured. The older test can also measure two different forms of vitamin D: Vitamin D2... found in fortified foods and... high-potency supplements that doctors prescribe... and Vitamin D3, the form of the vitamin that the body makes naturally after skin is exposed to sunlight.
The newer test can't distinguish between the two different types of D.
Holmes says vitamin D2 seems to confuse the tests. He says the tests' inability to accurately measure that form of the vitamin means that doctors can't tell if their patients are getting any benefit from it or if they're taking their supplements as directed.
... In absolute numbers, the reference test showed 33 patients out of 163 were deficient in vitamin D, while the Abbott test showed 45 people were vita

The Overtraining Training Trap

The Overtraining Training Trap. Tips to Spot and Avoid Overtraining
Written by Jeff Behar, MS, MBA   
In order to improve performance (gain size, strength and/or definition) you've got to work hard. However, hard training (be it heavy training, training with less rest between sets, more sets per work, or less days off) will break down your muscles and in the very short term, make you weaker.
To grow and to get stronger, the most important part of this equation is not necessarily how hard you train. To make the huge gains we all desire lifting success can not be thought of in a vacuum. An experienced athlete, who does include weightlifters and bodybuilders, understands the importance of proper nutrition and rest.
However, there are still many bodybuilders who do not realize (or at least underestimate) the important role rest plays in obtaining maximum performance and results from the hours spent in the gym.
 

The Value Of Rest

It is rest that makes you stronger, because it is the rest that allows the muscles that you have broken down to heal and recover. It is the rest that allows you to recover so you can be strong, and thereby handle the increased weight, and increased number of sets and reps needed to gain further.
Why does rest play such an important role in muscle recovery? It is during sleep where Growth Hormone (GH) levels are at their highest. Physiologic improvement in bodybuilding can only occur during the rest period following hard training. This is also why consuming the proper foods and supplements immediately following such training is key.

"...if proper recovery time (rest) is not given then the body can not regenerate."
Hard intense training (whether it is aerobic training which will challenge the cardiovascular system or weight training which will challenge the cardiovascular system to an extent and the muscular systems) conditions the body. Such workouts will improve efficiency of the heart, increase capillaries in the muscles bringing greater blood flow (more oxygen and nutrition), and increase glycogen stores and mitochondrial enzyme systems within the muscle cells (resulting in a much fuller look).
Immediately following a workout, during a recovery period these systems build to greater levels to compensate for the stress that you have applied. The result is that you are now at a higher level of performance. However, if proper recovery time (rest) is not given then the body can not regenerate.
The body will store less glycogen which is why you will look flat when you overtrain. If this imbalance between intense excess training and inadequate recovery (rest) time persists then performance will decline.
Without proper recovery time, not only will you reach a performance plateau, but you also will run the risk of injury, and may even experience reduced performance (less strength, less endurance, etc.).

Needed Rest Or Just Plain Lazy?

It is important to be able to discern the difference between needed rest and just laziness. There are a lot of factors that can contribute to how you are feeling and how your body will respond.
These Factors Include:
  • Stress
  • Sleep
  • Nutrition
  • Physical condition
  • Emotional state
  • Recuperation time; not necessarily in order of importance.
Regardless of whether I have a show or not I will always listen to my body when it comes to training and recuperation.

"The amount of rest and recovery time an individual needs will vary from person to person."
Having been training for over 25 years I follow instinctive training to gauge whether or not I need rest. How much I train, how often, how fast, how long and how heavy will all depend on my energy levels and how I feel.
Sometimes, I will opt to take a day off in the middle of my training split; sometimes I may slide a body part to the next day if my energy is off. Sometimes I won't even take a day off and I might cycle through my routine 2x before taking the day off. It will all depend as to how I feel.
Because the mind can sometimes be tricky, in many cases I will always drive to the gym and attempt my workout to see if my lethargy is real. I have found that approximately 50% of the time once I get to the gym and start my workout I not alone have an amazing workout but I actually feel better (endomorphin release). Making myself go to the gym prevents my mind from psyching me out of a workout because I know I am forcing myself there.

Defining Overtraining

So what exactly is overtraining for a bodybuilder? Overtraining can best be defined as the state where your body has been repeatedly stressed by training (weight training and/or cardio) to the point where rest is no longer adequate to allow for recovery.
There Are Two Main Types of Overtraining:
  1. Localized
  2. Systemic overtraining
Both can occur as a result of too much exercise/stress without enough recover time/rest and proper nutrition. Localized overtraining is the most common. As the name implies, localized overtraining effects a specific muscle or muscle group without affecting other muscle groups.
The most common cause of localized overtraining is when the same muscle group is trained on successive days or with too much frequency without adequate amounts of rest. This can also occur when supporting muscle groups are trained on separate days, thereby never given these muscles a chance to recover.


"It is very common for bodybuilders, power lifters and fitness competitors to experience localized overtraining."
Systemic overtraining occurs must less frequently and is potentially the more serious of the two types of overtraining. Systemic overtraining will affect the entire body causing the body to enter a negative nitrogen balance (a catabolic state). As the body enters this state the body also produces an increased amount of cortisol.
Cortisol is a hormone secreted by the adrenal cortex in response to stress. Cortisol impedes muscular repair and function, decreases testosterone production, inhibits protein synthesis, accelerates proteolysis (protein breakdown) and inhibits muscular growth. Making matters worse it also reduces the body's ability to use fat as an energy source, increasing the amount of stored fat within the body.

Signs Of Overtraining

There are many signs of overtraining. Physical symptoms include elevated morning pulse (10 beats more than normal), consistently elevated blood pressure, lack, persistent muscular soreness, increased frequency of common illnesses, like colds, increased incidence of injuries, and decreased appetite and weight loss. The effects from overtraining may not only by physiological.
Emotional & Behavioral Symptoms Can Also Occur Such As:
  • Irritability
  • Mood swings
  • Insomnia
  • Depression
  • Loss of desire to train (or do other things formerly enjoyed).
Emotional and behavioral symptoms typically will only occur as a result of chronic (long term) overtraining (weeks to months). This condition is best known as "burnout"."
This condition is different from short term overtraining in that post exercise fatigue and emotional swings persist even after recovery periods that are taken.

The Overtraining Threshold

The exact threshold for overtraining will vary among individuals, as everyone responds differently to exercise and stress. Some weightlifters can tolerate large volumes of sets and heavy weights while others can tolerate much less.


"Regarding training volume the number of sets should be reasonable as not overtax your neuromuscular system and deplete your energy reserves."
Several factors such as nutrition sleep quality, hormonal and enzymatic concentrations, muscle fiber composition, and previous training experience can impact recuperative capacity and, therefore effect when overtraining will occur.
Although everyone has varying recuperative abilities, a period of 48 to 72 hours is usually required for adequate recovery between strength training sessions.
For most people 8 hours of GOOD sleep is also a safe bet. Even the most experienced bodybuilders typically do not train large muscle groups more than ten to twelve total sets while subjecting smaller muscle groups to only eight to ten sets.

Studies

There have been several clinical studies done regarding overtraining. One interesting finding is that in many individuals overtraining increased the body's cortisol levels and dehydroepiandrosterone (DHEA). DHEA and cortisol are the body's long-acting stress hormones and are antagonistic to each other to some degree.
DHEA has an anabolic or building influence, while cortisol has a catabolic or tearing down effect on the body. Normally these hormones are in balance.
They become imbalanced during chronic overtraining. After proper rest and recovery, the body will reduce its output of cortisol and DHEA to resting levels. This is what happens with short episodes of stress. However, if proper recovery is not obtained such as in chronic overtraining conditions, the body will continue to make increasingly greater amounts of cortisol, while reducing the amount of DHEA produced.
Elevated Levels of Cortisol Can:
  • Cause you to crave carbohydrates excessively especially in the evening 
  • Make you feel fatigued and exhausted 
  • Increase cholesterol and triglyceride production 
  • Decrease serotonin levels in your brain which can trigger depression. 
  • Deplete vital vitamins and minerals the body needs for proper function such as the B (aka, stress vitamins), Calcium and magnesium
The consequences of elevated cortisol and reduced DHEA can be devastating. Although the effects from high cortisol and low DHEA levels will vary with each individual and will also be dependent upon genetics, lifestyle and environmental factors.
The Negative Effects May Include:
  • Reduced growth hormone (GH) release, which related to reduced muscle mass and strength, increased fat tissue, a weakened immune system and other health declines. 
  • Reduce protein synthesis. 
  • Increased protein breakdown, which can lead to muscle loss, bone loss, arthritis, and overall muscle weakness. 
  • Immune system compromise with increased risk to infections, certain and disease. 
  • Thyroid function impairment resulting in decreased metabolism, and increased fat storage. 
  • Glucose utilization and insulin function impairment resulting in higher blood sugar levels. 
  • Salt and water are retention, which can raise blood pressure (this can be deadly if anabolic aids which can also raise blood pressure through fluid retention are also used). 
  • Increased blood cholesterol and triglyceride levels increasing the risk for heart disease. 
  • Disrupted sleep patterns. 
  • Reduced R.E.M. (rapid eye movement)
Overtraining has also shown to cause an increase in the amount of free radicals within the body. This can serve to exacerbate the catabolic effects of overtraining, making symptoms worse.

Treatment For Overtraining

The treatment for the overtraining sounds very simple - rest and proper nutrition. However, there are many different opinion regarding what is proper rest and what is proper nutrition. The can be further complicated for the pre-contest competitive bodybuilder who is increasing training while trying to control caloric intake.
Rest & Relaxation There are many ways a bodybuilder can rest and reduce elevated cortisol levels. The most obvious method is to increase sleep (and I mean good quality R.E.M. sleep). This will increase GH levels and reduce cortisol levels.
There are also other positive methods to reduce stress and aid in recovery. Such methods may include massage (which also increases blood flow to the muscle to aid in recovery), meditation, and yoga.


"Reducing caffeine and other stimulants is also important since they negatively affect sleep patterns."
Caffeine also stimulates the pituitary gland which also can raise cortisol and dopamine levels, which are the same neurotransmitter that makes heroin, amphetamines and cocaine which is one reason why some find caffeine addicting (some have found success using tyrosine supplementation to raise dopamine levels in the absence of caffeine).
Rest - How Much Is Enough? To make gains a bodybuilder must straddle the line between challenging (stress) the body and rest. Unfortunately the amount of rest each person needs is also once again dependent upon genetics, lifestyle and environmental factors.
Studies show that as we age we need less rest, but those studies are not geared towards competitive bodybuilders. The best recommendation I could give to a bodybuilder regarding what is the proper amount of rest is to advise him to listen to his/her body.
The real key to success is to be able to detect the signs of overtraining early and to take the needed rest. This needs to happen even if you believe you do not have the time, and "your body is not ready for your contest". It is important to remember that in many cases more training will not be best, and will only result in a worse appearance. What is important is to train hard while you are in the gym, get the best nutrition and rest when you are out of the gym, and the rest (no pun intended) will follow.
Nutrition & Supplementation Regarding nutrition, nothing beats a good balanced diet. Consuming quality carbohydrates, especially post-workout, helps to replenish glycogen stores and provide sufficient energy for intense training. It is also imperative to maintain an adequate amount of good quality protein.
There is an abundance of evidence that weightlifters need up to 2x the amount of protein than the average person. As a minimum, serious weightlifters should consume approximately one gram of protein per pound of bodyweight to maintain a positive nitrogen balance. This means that a 200 pound bodybuilder should consume 5 protein meals of approximately 40 grams of protein.
It is understood that this can be difficult sometimes do to today's fast paced environment, as well as during pre-contest time. Therefore the use of high quality supplements can be useful in preventing protein breakdown.
Overtraining can deplete minerals such as zinc, magnesium, manganese, calcium, and vitamins B6, Pantothenic Acid (B5) and vitamin C. Additional supplementation of these vitamins and minerals are highly suggested.
Anti-oxidants such as Vitamin C, Vitamin E, co-enzyme Q10, alpha-lipoic acid, and selenium should also be used since they have been proven effective in combating free radicals that form as a result of overtraining.
A DHEA supplement is also desirable because DHEA is antagonistic to cortisol. 7-Keto DHEA is preferred by many bodybuilders because it is considered a more potent form of DHEA that will not be converted to active androgens (testosterone) and estrogens which will cause further water retention and a "soft" look.
Glutamine supplementation should also be considered to replace glutamine stores used during the workouts, boost the immune system and to prevent protein breakdown. Arginine and ornithine supplementation is suggested to increase growth hormone levels.

Conclusion

The best defense to overtraining is a proper combination of god rest and proper nutrition. A well-planned training program will include adequate recovery time and proper nutrition, including proper supplementation.
Most importantly listen to your body when you see the early warning signs of overtraining. Be flexible and adjust your workout, your sleep and your diet accordingly.
Understanding the signs of overtraining and responding accordingly will help you reach your goals faster.
