How to do it

1. Stand with your feet hip-width apart and extend both arms straight out to the sides at shoulder height.
2. Rotate one arm from the shoulder so the palm faces up and the other so the palm faces down, then twist both arms at the same time to switch: the palm that was up turns down, the palm that was down turns up.
3. Keep your arms straight and level throughout and let the rotation come from the shoulder, not the wrist.
4. Keep the movement smooth and unhurried - this is a mobility drill for the shoulder joint, not a race.
