Injury: Shoulder Impingement
A shoulder impingement, or rotator cuff tendonitis, is a common injury for swimmers, overhead ball throwers and racquet sport enthusiasts. It occurs when the tendons or bursa surrounding the shoulder rub against the shoulder blade itself. It usually starts as a dull ache but if left untreated it can sideline you for several weeks and in severe cases can even lead to surgery. The supraspinatus, a small muscle in the upper back that runs from the shoulder blade to the humerus, is often where the tightness and inflammation of shoulder impingement begins. The supraspinatus stretch will feel awkward at first as it's a small and hard muscle to reach, but you'll notice its positive effects almost immediately afterward.
Stretch: Supraspinatus stretch
Place your right hand on your right hip and rotate your arm so that your elbow is facing forward. Take your left hand and hold onto your right arm to gently pull it more forward until you feel a good stretch. Hold this position for 30 sections before switching sides.
