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.
This primary muscle is called an âagonist.â Itâs the main muscle that undergoes either isotonic or isometric contractions in order to produce or maintain a motion. Each major section of the body contains these agonist muscles that are responsible for primary movement.he deltoid is the major shoulder muscle responsible for moving the shoulder joint. The rotator cuff is a muscle group that includes the teres minor, infraspinatus, supraspinatus and subscapularis muscles, which together provide stability and allow the shoulder to rotate.
