- ROTATOR CUFF INJURY
Four main muscles (supraspinatus, infraspinatus, teres minor and subscapularis) comprise the rotator cuff, which surrounds and stabilizes the shoulder joint. Shoulder pain when you reach behind you, overhead or out to the side may be a sign of a rotator cuff strain. “It typically results from repetitive overhead activity,” says Luga Podesta, M.D., sports medicine specialist at Podesta Orthopedic and Sports Medicine Institute.
Activities such as swimming or throwing a ball and overhead shoulder movements like military presses can lead to rotator cuff strains when done repeatedly over time. HOW TO STAY SAFE: Strengthen your rotator cuff muscles as part of your upper-body program. Use good posture (a slouched posture makes you more prone to compression of the shoulder joint) and avoid repetitive overhead exercises with weight that’s too heavy and lat pulldowns behind the neck — do pulldowns in the front instead.
