The Benefits of Interval Training


Have you ever wondered why we use interval training in BUTI workouts? The good old days of running on the treadmill at a decent pace for 45 minutes are LONG GONE! Interval training is fair superior in a variety of areas: performance, speed, cardio, fat burn and adaptation. If you've ever taken a class with Founder Bizzie Gold, you know that she always reminds you that you'll see dramatic improvement from your first class to the second. BUTI is the ideal cross-training workout for anyone looking to burn fat, stretch and sculpt. Our intervals include yoga-based stretching during our rest interval and high-intensity dance and plyometric exercises during our work interval. This is how interval training works:

"Interval training works both the aerobic and the anaerobic system. During the high intensity efforts, the anaerobic system uses the energy stored in the muscles (glycogen) for short bursts of activity. Anaerobic metabolism works without oxygen, but the by-product is lactic acid. As lactic acid builds, the athlete enters oxygen debt, and it is during the recovery phase that the heart and lungs work together to "pay back" this oxygen debt and break down the lactic acid. It is in this phase that the aerobic system is using oxygen to convert stored carbohydrates into energy.
It's thought that by performing high intensity intervals that produce lactic acid during practice, the body adapts and burns lactic acid more efficiently during exercise. This means athletes can exercise at a higher intensity for a longer period of time before fatigue or pain slows them down. "

According to the American College of Sports Medicine, more calories are burned in short, high intensity exercise. If you are counting calories burned, high intensity exercise such as intervals are better than long, slow endurance exercise." (ACSM.org)
