When making a fitness plan, what is the approximate range of the number of groups in each movement?
Group 4-6, 6- 12RM, the rest time between muscle building groups is 1-2 minutes, and the rest time between movements is 3-5 minutes. A large muscle group like the chest needs 16-20 groups to train completely, so it is four movements, and a small muscle group like the arm is 9-655.
