Reverse Machine Flyes target the rear shoulders (rear delts) and upper back (mid-back) to improve posture, stability, and shoulder balance. Sit at the machine with your chest against the pad, grasp the handles, and move your arms outward to shoulder height while keeping elbows slightly bent. Slowly return to the starting position. This controlled movement isolates the rear delts and strengthens stabilizing muscles. Gymcheq helps you stay confident and precise with each rep.
