How to do it

1. Stand tall and raise both arms straight up overhead, hands together.
2. Keeping your upper arms still and your elbows pointing forward, bend at the elbows to lower your hands behind your head, then extend back up to the full overhead reach.
3. The upper arms are pillars - they stay glued beside your ears while the forearms do all the traveling.
4. Squeeze the back of the arms at the top of every extension and they'll know exactly whose exercise this is.
