Cable Single-Arm Reverse 45-Degree Fly

Set the cable pulley to a high position and attach a single handle, standing sideways to the machine.

Grab the handle with your outside hand, keeping a slight bend in your elbow throughout the movement.

Brace your core and pull the handle outward and upward across a 45-degree angle away from your body.

Pause briefly at the top as you squeeze your rear shoulder and upper back muscles.

Slowly return the handle to the starting position in a controlled manner before repeating for your desired reps.
