Have the pulley at elbow height with a handle attached.
Stand sideways to the cable machine and grasp the handle with one hand.
Position this elbow against the side of your body, with your elbow at 90 degrees and your forearm resting against your stomach.
Maintain a good posture and move the weight away from your body as far as you can without rotating your body.
Try to maintain a 90 degree angle with your forearm.
Slowly allow the weight to return back to the starting position.
