Set the cable pulley about shoulder height with a rope attached. Take a few steps back to get tension in the pulley. Set feet in a shallow lunge position. Pull elbows back and slightly up, thinking about initiating the exercise with the rear deltoid and not the hands. Slowly release the weight, keeping body stable. Tip: To keep this exercise out of your trapezius muscle and in your deltoid, keep your neck relaxed and your shoulders pressed down.
