The Supreme 90-Day Workout is an exercise program that utilizes the technique of muscle confusion to accelerate the burning of body fat and increase lean muscle growth. Muscle confusion is the idea that by changing workouts constantly, the body cannot easily adapt to the exercises.
The workout package includes a set of 10 DVDs hosted by fitness personality and author Tom Holland and the book "Supreme Nutrition" by Tosca Reno. Five of the DVDs are devoted to strength-training routines for building lean muscle, three of the DVDs cover cardiovascular, fat-burning exercises and two DVDs are for core and abdominal workouts. The exercise program is similar to the competing product P90X.
