Do this exercise up against a wall.
Make sure your lower back, shoulders, and head are touching the wall.
Bring your arms out to the side so that your elbows, wrists and hands are touching the wall.
Your elbows will be bent.
Try to raise your arms above your head as much as you can without coming away from the wall.
Keep your shoulder blades squeezed together.
If you feel that your elbows and your wrists are coming away from the wall as you raise your arms up, you need to stop at that position and lower your arms back down.
