Cow Face Pose

Reach one arm straight up, then bend it so your hand drops behind your head and between your shoulder blades. Bring your other arm down by your side, bend it, and reach up your back from below to meet the first hand, or as close as you can get. If your hands don't meet, hold a strap or cloth between them instead of straining to close the gap — the stretch works the same either way. Keep your top elbow pointing up rather than letting it drift forward, and switch which arm goes on top to work both shoulders evenly.
