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.
This is called antagonistic muscle action. The working muscle is called the prime mover or agonist. (it s in agony!) The relaxing muscle is the antagonist. The other main pair of muscle that work together are the quadriceps and hamstrings.The prime mover is helped by other muscles called synergists.These contract at the same time as the prime mover. They hold the body in position so that the prime mover can work smoothly.it s in agony!) The relaxing muscle is the antagonist.
