What is machine leaning?

The sequence shown below is one way to order the exercises. The large muscles of the lower body are normally trained before the smaller muscles of the upper body, because these exercises require more mental and physical energy. The core muscles of the torso are trained before the shoulder and arm muscles that assist them. Exercises often alternate between "pushing" and "pulling" movements to allow their specific supporting muscles time to recover. The stabilising muscles in the waist should be trained last.
