Stand upright holding one end of a resistance band in the hand of your affected arm.
Stand on the other end of the resistance band using the foot on your unaffected side.
The hand holding the band should be located downwards and across your body and located in front of your hip on the opposite side of the body to the affected arm.
Your thumb should be facing inwards.
Maintain good posture and shoulder blade control throughout the following movement.
Keep your arm straight and pull the band upwards and outwards, diagonally across your body, rotating the arm.
Continue in a fluid motion and finish the movement with your arm outstretched and away from your body with your thumb facing upwards.
Slowly return to the starting position and repeat.
