Sleeper Stretch

How to do it

1. Lie on your side on a firm surface, on the side you want to stretch.
2. Raise that arm to shoulder height in front of you, elbow bent 90 degrees, fingers pointing up.
3. Using your other hand, gently press the raised forearm down toward the floor.
4. Stop when you feel a stretch at the back of the shoulder; do not force through pain.
5. Hold for the set time, release, and repeat before switching sides.
