Cable Bent Over Rear Delt Fly works the rear shoulders (rear delts) and upper back (mid-back) to improve posture, stability, and shoulder balance. Stand bent over slightly with a cable handle in each hand, palms facing each other. Lift your arms out to the sides until they reach shoulder height, then lower slowly under control. This exercise helps correct rounded shoulders and strengthens stabilizing muscles. Gymcheq helps you stay confident and precise with each rep.
