Upper Body. The primary muscles in the upper body that are used when performing a golf swing are the shoulders and back muscles. As with all muscles involved in the swing, it is important for the upper-body muscles to be both fit and flexible.
Here is a photo of the great Ben Hogan demonstrating how to throw a ball simulating the motion of a good golf swing, transferring weight from the back leg to the forward leg. The golf swing involves mainly rotation of the body. In the rotation, however, the weight of the body does shift from one leg to the other. As the shoulders rotate in the backswing, the weight of body changes from being 50% on both legs at address, to 70-80% on the rear leg at the top of the backswing, to 70-90% on the front leg by impact. Note the position of the upper body of Tiger in different stages of the swing.
