Cable External Shoulder Rotations target the rear shoulders (rear delts) and rotator cuff muscles to improve shoulder stability, mobility, and injury prevention. Stand next to a cable machine with the handle in one hand, elbow bent at 90 degrees and tucked to your side. Rotate your arm outward, keeping your elbow close to your body, then return slowly. This controlled movement enhances shoulder health and functional strength. Gymcheq helps you stay confident and precise with each rep.
