Teres major muscle

The teres major muscle is a muscle of the upper limb and one of six scapulohumeral muscles.

The teres major is a medial rotator (internal rotation) and adductor of the humerus and assists the latissimus dorsi in drawing the previously raised humerus (upper arm) downwards and backwards (extension, but not hyper extension).

The Role of the Teres Major in the Golf Swing

The teres major plays an important role in moving the right arm correctly during the downswing, and thus efficiently transferring energy to the golf club.  For a description of this action, see The Role of the Right Arm in the Golf Downswing.
