Stand up straight with your arms by your side.
Tie a resistance band to a solid object to the side of your good arm.
Hold the other end of the band in your affected hand and bend your elbow to 90 degrees.
Turn your forearm outwards, pulling against the resistance of the band.
Keep your upper arm by your side.
Make sure your body stays still and does not twist towards your arm.
Control the movement as you bring your arm back in towards your tummy.
