Lie on your back holding a stick in both hands across your body.
Bend your elbows so that the stick lies across your chest.
Your hands should be around shoulder width apart, or wider if this is more comfortable.
Using your unaffected arm to assist, lift the stick directly up into the air above your chest.
Control the movement as you lower the stick back to your chest.
Next, lift the stick directly up above your head.
Control the movement as you lower the stick back to your chest.
Finally, straighten your elbows as you reach the stick towards your hips.
Control the movement as you bring the stick back to your chest.
Repeat these three movements.
