This is the P90X3 Mass Workout Schedule, which is different than the normal P90X3 Classic Workout Schedule as this schedule focuses on building mass or muscles and less focus on cardio. For all people that have never tried P90X3 I would always recommend starting with the P90X3 Classic Schedule as it will give you a great overview of how P90X3 works, along with letting you experience how the program was designed. P90X3 Mass is great for those that want to grow and get big as the focus is more on resistance workouts with pullups and pushups, and dumbbell workouts, with less focus on the cardio to make you lean out. If you want to get strong and ripped, this is the workout for you. Give it a shot today!
