This exercise strengthens the muscles that stabilize your scapula (shoulder blade) and that rotate your humerus (upper arm bone). The resistance of the band acting on your shoulder teaches it to remain engaged and stable while your humerus moves. This is critical for preventing chicken winging and can also improve shoulder stability while climbing.
