What Does Core Strengthening Actually Mean?

By: Marty Zackroff, MBT

Many of us have heard it is very important to keep your core strong. But how many people really know what core strengthening means? Here is an explanation of what the core is and why it is so important to keep strong.
The following are the most important muscles involved in core strengthening:

• Transversus Abdominis. This is the deepest of the abdominal muscles and a key stabilizer of your spine.

• Multifidus. A short muscle that is located on your spine. Its main function is to stabilize your spine.

• Obliques. These muscles rotate and side-bend your spine.

• Rectus Abdominis. This is the muscle that is most aesthetically pleasing; otherwise known as the “six-pack” muscle. Its function is to flex or curl the trunk.

• Erector Spinae. The muscles that run along your spine which help you stand up straight.

In addition to these muscles, there are many more that attach to your spine and function to move your body, but the above list are the most important, especially the first two.
The reason, “keeping your core strong” has become such an important part of everyone's workout, is because research has shown the stronger these muscles are, the less stress and strain there will be on your back. Let’s explain this a little further.
Many people feel low back pain when lifting something that is heavy. The proper coordination of your body should contract your abdominals/core muscles greater than your low back muscles. However, if a person’s core muscles are not strong enough to tolerate the weight of heavy object your brain will recruit the help of your low back muscles. This is when people feel the pain and become injured. This explains why core strengthening is very important.
