INTRODUCTION Exercises to promote shoulder girdle stability are integral components of strength and conditioning, rehabilitation, and postrehabilitation exercise programs for clients who perform repetitive overhead motions during sports or occupational activities (2,3, 6–12). Functional imbalances between the upper trapezius and the lower trapezius, middle trapezius, and the serratus anterior muscles have been associated with conditions like shoulder instability and subacromial impingement syndrome, which can cause shoulder pain and dysfunction (2–4,6–12). This article is not meant to help readers diagnose or treat shoulder pain or injuries. Clients should be free of shoulder or upper-extremity injuries and related pain before performing these exercises. The onset of injury-related pain warrants termination of exercise and immediate client consultation with a physician, physical therapist, or other health care provider.
