Attach the cable to your Arm Anchor and begin with your working arm reaching across your body, keeping a slight bend in your elbow. For the traditional reverse fly, set the pulley around shoulder height and stand upright. Sweep your arm outward until it is extended to your side, squeezing your rear shoulder. For the low-to-high variation, set the pulley low, hinge forward at your hips, and brace your free hand on your thigh. Raise your working arm diagonally outward and upward. Slowly return to the starting position, keeping your elbow bend consistent and avoiding twisting or swinging your torso.
