Shoulder External Rotation (With Cable) Strengthening the muscles that support your shoulder will help keep your shoulder joint stable. Stand, hold the cable (or resistance band), bend the elbow upward to 90 degrees, and hold your upper arm at the side of the body. Place the body such that the cable pulls sideways toward the inactive arm. The target muscles are the shoulder external rotators. What muscles does external rotation work? In red we can see how the infraspinatus muscle externally rota

Cable external rotation This exercise can: - improve shoulder stability & forward shoulder posture - reduce the risk of shoulder injury Left top (incorrect): - too much arm abduction (arm moving out to the side, away from the body) Bottom left (incorrect): - the line of resistance (gravity) is perpendicular to the line of action (movement). - this is external rotation however, when performed with DBs, the supraspinatus, biceps & forearm flexors work more than the target muscles.
