Split system training is a weight training program that separates workouts by body parts, usually these are separated exercises for the upper and lower body. For example, a strength training program will include a lower-body split on Tuesdays and an upper-body split on Thursdays.

The split training program can become more specific if you narrow the division into the upper and lower parts of the body to certain muscle groups (for example, legs, buttocks, arms, back, chest and abs).
