Benefits of high-intensity interval training

One of the main benefits of HIIT is adaptability – unlike many more specialized workouts, it can easily be modified for all fitness levels. And, HIIT programs can be built around many exercise modes, from biking, to swimming, to group exercise classes.

Fitness-wise, because of their vigorous nature, HIIT workouts burn more calories after a session is over than other traditional workouts. Studies have shown that HIIT workouts also improve:

Aerobic & Anaerobic Fitness

Blood
Pressure

Cardiovascular Health

Insulin Sensitivity

Cholesterol Profiles

Abdominal fat and body weight while maintaining muscle mass

This mornings workout was a grind! Katie coached a couple of combinations I had never done before. It was GREAT! I love it and feel better about myself everytime I leave this gym.
