Set up a cable station with a handle attachment at the bottom of the pulley. Stand facing the cable and the grip the handle firmly with one hand. Stand with your feet hip width apart with a straight back and your core braced. Ensure you are far enough away from the cable to keep tension on it throughout the movement. With a slight bend in the knee, hinge your hips back. Your arm should be extended directly out in front of you. Keeping your arm straight (but not locking out your elbow) proceed to pull the handle towards your torso, exhaling as you do so. Pause for a count of one, squeezing your back muscles and return to the start position, inhaling as you do so. Repeat all the required reps (or time) on one arm before changing to the other.
