In this split, the whole body is worked over a period of four days: Day 1 - Chest/Back. Day 2 - Thighs/Hamstrings. Day 3 - Shoulders/Calves. Day 4 - Biceps/Triceps/Abs. Training Notes. Because this workout splits the body over four days, you can do more sets for each muscle group.
1 Try a different set each time you work out your pecs to get a full workout. 2  Your pectorals are not one muscle, they are a set of interrelated muscles. 3  Certain exercises will focus more on one section than another, so a variety helps you build the whole muscle group.
