Exercise Advice: Using a cable machine, attach a cable handle to the top portion of the machine. Grab the cable handle with your right hand and your palm facing up. Slowly position your body so your right knee is on the ground and your left knee up as displayed in the exercise photo. The starting position should have your hand at about chin level. While keeping your elbow tucked in at your side, slowly extend your arm down until almost reaching a full locked out position at the bottom. Always keep a little bend in your arm at the extended position to keep tension on the triceps and off your elbow joint. Finally, slowly let your arm move back up into the starting position. Repeat with your opposite arm and change your leg accordingly from right to left.
