what muscle groups do you work together in a 4 day workout
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.
