The Principle of Arrangement of Exercise

A weight-training program should include exercises for all major muscle groups. For optimal efficiency during weight-training, the exercises in a weight resistance program should be arranged so that the larger muscle groups are exercised before the smaller ones. Smaller muscles tend to fatigue sooner and more easily. Therefore, in order to ensure proper overload of larger muscle groups, they should be exercised first. The larger leg muscles should, for instance, be exercised before the smaller arm muscles.
