Stand facing a wall about an arm's length away, with your hands on the wall at shoulder height. Bend your elbows to bring your chest towards the wall, then push back until your arms are straight. At the end, push a little further so your shoulder blades spread apart on your back.
If an exercise hurts more than you expect, stop and contact your clinician.
