The 5/3/1 bodybuilding program is a variation of the 5/3/1 strength training program that is focused on bodybuilding goals, such as increasing muscle mass and aesthetics. This program incorporates the same basic principles of the 5/3/1 program, including the use of the four main lifts (squat, bench press, deadlift, and overhead press) and the concept of progression through incremental increases in weight and volume. However, the bodybuilding program places more emphasis on assistance exercises and higher volume training, with a greater focus on hypertrophy and muscular endurance. The program includes three main lifts each training day, along with multiple assistance exercises that target specific muscle groups.
