Stand to the side of a cable machine with a handle in the arm to be exercised furthest.
The cable should cross in front of you from around knee height.
Your legs should be wider than hips width with a bend in your knee.
Lean your body forwards from your hips, keeping your back straight and your gaze directly down.
Relax the arm with the cable vertically downwards.
Tighten your abdominal muscles, then lift the weighted arm directly out to the side with your elbow soft.
Ensure your body does not rotate with the movement.
Control the movement as you lower the arm back down and repeat.
