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.
Chest and Shoulders. The primary muscles responsible for movement of the chest and shoulders are the pectorals, the deltoids, the rotator cuff and the trapezius. The pectorals, which cover the chest, include the pectoralis major and minor muscles.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.
