Sit up straight on a firm surface.
Do not lean back onto any supportive rest.
Keep you posture upright throughout this exercise.
Hold a tensioned resistance band in your weaker hand.
Rest your unaffected arm on your lap.
Use a small movement to bring your shoulder blades backwards and downwards.
Slowly pull the band back towards you keeping your elbow close to your body.
Then slowly let the band recoil as you bring your arm forwards again.
Ensure your shoulder blade stays backwards and downwards throughout the exercise.
