The Mike Mentzer Program is a high-intensity training (HIT) system that aims to maximize muscle growth in minimal time. It is based on the principles of Arthur Jones, the founder of HIT, but modified by Mike Mentzer, a former professional bodybuilder and Mr. Olympia contender. The program involves performing one set of 6-10 repetitions per exercise, using a weight that causes failure or beyond. The program also uses advanced techniques such as forced reps, negative reps, rest-pause, and pre-exhaust supersets to increase the intensity and stimulate the muscle fibers. The program requires a lot of recovery time between workouts, as the muscles need to adapt to the stress and grow stronger. The program is suitable for experienced lifters who want to challenge themselves and break through plateaus.
