Comments and tips
Keep your elbow locked to your side and bent at a 90-degree angle.
Place a towel under your elbow. If it drops, it means that you are not keeping your elbow locked to your side.
The cable external shoulder rotation exercise has been included in the training programs to promote shoulder health, which makes it very important. Your infraspinatus, teres minor, and posterior deltoid are external shoulder rotators, whereas your latissimus dorsi, pectoralis major, teres major, anterior deltoid, and subscapularis are internal shoulder rotators. Unfortunately, most popular training programs strengthen internal shoulder rotators much more than they do external shoulder rotators, with the infraspinatus and teres minor hardly getting any attention. This can lead to a muscle-strength imbalance, which can destabilize the shoulder joint (rotator cuff) and cause pain and injury. Therefore, do not omit this exercise!
