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.
Generally speaking, for a non-professional body builder or athlete, if you want growth, you should work it hard, aim for 6-10 reps for 3 sets through a multi-joint exercise (lat pull-downs, curl ups, rows) and then give it 48 hours to recover. So every other day you could work a muscle group if you work it hard enough.
