This exercise requires an assistant.
Lie on your back with your arms relaxed by your side.
Have an assistant support your arm at the wrist and at your upper arm.
Slowly ask the assistant to lift up your arm until it is pointing directly up to the ceiling.
Ensure that you try to assist in the movement as much as you can.
Hold this position before returning your arm back down to your side with the assistant helping to take some of the weight.
