What is a split routine?
The split routine system is a way to train various body parts on alternate days. A split routine system allows the training intensity to be higher than would be possible if four to six sessions were combined into two or three long sessions of equivalent training volume. It is possible to develop split routines in which the total training volume per body part is higher than that in a typical total body training session because in a split routine each training session is dedicated to a smaller number of body parts or muscle groups.
