You will need an assistant for this exercise.
Lie on your back with a buoyancy collar around your neck and a noodle under your hips.
Loosely hold onto the wall with your nearest hand, you will be exercising your opposite shoulder.
Take your arm out to your side and ask your assistant to stand between your shoulder and your hip.
Your assistant will then hold onto your upper arm near the shoulder joint with both of their hands.
Using their elbows for leverage, your assistant will then gently stretch your arm further away from your side.
Hold this position.
