High Intensity Interval Training

March 28, 2010

HIIT is a specialized form of interval training that involves short intervals of maximum intensity exercise separated by longer intervals of low to moderate intensity exercise. It is designed for people whose primary concerns are boosting overall cardiovascular fitness and fat loss without losing the muscle mass they already have.

Benefits:

Conditions both your anaerobic and aerobic energy systems.

Increases the amount of calories you burn during an exercise session and afterward because it increases the length of time it takes your body to recover from each exercise session.

Causes metabolic adaptations that enable you to use more intramuscular fat as fuel under a variety of conditions. This will improve your athletic endurance as well as your fat burning potential.

Appears to limit muscle loss that can occur with weight loss, in comparison to traditional steady-state cardio exercise of longer duration. Less muscle loss means higher resting metabolism.

Strengthens the heart resulting in lower resting heart rate a accelerated recovery after workout.
