Insanity

INSANITY uses MAX Interval Training, which replaces traditional moderate-intensity exercise with maximum-intensity exercise, and trades short intervals of intensity for short periods of rest.
 
Adding high-intensity exercise forces the body to use fast-twitch muscle fibers not normally engaged in cardio exercise. These fast-twitch fibers continue burning fuel even during lower-intensity exercise.
