The P90X workout DVD program consists of 12 high-intensity DVD workouts that target all major muscle groups through a technique called "muscle confusion" to prevent plateaus. It includes workouts for chest & back, shoulders & arms, yoga, lower body, martial arts, stretching, core, chest/shoulders/triceps, back/biceps, cardio, and abs. The program provides a nutrition plan and supplement options to enhance results, and the DVD workouts are led by trainer Tony Horton to keep users engaged throughout.
