"High-intensity interval training (HIIT) describes any workout that alternates between intense bursts of activity and fixed periods of less-intense activity or even complete rest. For example, a good starter workout is running as fast as you can for 1 minute and then walking for 2 minutes. Repeat that 3-minute interval five times for a 15-minute, fat-blasting workout. It sounds too simple to be effective, but science doesn't stretch the truth. Read on for eight proven benefits of HIIT: 1: Efficient HIIT is the ideal workout for a busy schedule. Research shows you can achieve more progress in a mere 15 minutes of interval training (done three times a week) than the girl jogging on the treadmill for an hour. 2. Burn More Fat and Increases Your Resting Metabolic Rate You burn more fat and calories after a HIIT workout than you do after, say, a steady-pace run. 3. Increase Hgh Levels In addition to increased fat burning and more muscle preserved, HIIT stimulates production of your human growth hormone (HGH) by up to 450 percent during the 24 hours after you finish your workout. This is great news since HGH is not only responsible for increased caloric burn but also slows down the aging process, making you younger both inside and out! 4. Burn More Fat and Not Muscle Studies show that both weight training and HIIT workouts allow dieters to preserve their hard-earned muscles while ensuring most of the weight lost comes from fat stores. 5. Improved Cardio A 2006 study found that after 8 weeks of doing HIIT workouts, subjects could bicycle twice as long as they could before the study, while maintaining the same pace.
