Max Interval Training

What is Max Interval Training ?

Max Interval Training is based on the fundamental philosophy of High Intensity Interval Training, but adds a twist. Like HIIT, Max Interval Training workouts are performed at the highest possible level of effort. But rather than short bursts of high-intensity exercise, Max Interval Training sessions are longer, still at maximum effort, with shorter periods of rest.

Each workout is a continuous challenge of alternating between aerobic and anaerobic intervals performed at your max, potentially burning over 1000 calories per session. Thousands of INSANITY users have reported previously unattainable results.

Intensity is the key. Intervals must be performed at 100% effort. Shaun T.’s innovative motivational techniques will help you maintain the required intensity levels throughout each DVD workout.

Like HIIT, Max Interval training cranks up your metabolism, increasing Resting Metabolic rate (RMR), which aids in burning fat continuously even when at rest or asleep. It can also increase the release of post-exercise endorphins.

The body is a highly adaptable machine. As you continue any type of training without mixing it up, progress will slow, and sometimes even stop completely. Max Interval Training confuses the body by constantly altering the training protocol. Many studies confirm that it also improves performance in already well-conditioned athletes, in addition to an increase in endurance, ability to recover faster and overall energy level improvement.


Many Beachbody fitness programs promote a memorable catch phrase or fitness philosophy. I wanted to dig deeper and find out what these terms really mean from a scientific and physiological viewpoint.
TurboFire focuses on High Intensity Interval Training (HIIT), sometimes called sprint interval training — Read our HIIT article here. P90X is all about Muscle Confusion. With INSANITY, Shaun T. has introduced a new term — Max Interval Training or MAX HIIT.
