How to do it

1. Stand tall with your feet hip-width apart and your arms at your sides.
2. Sweep one arm up and back overhead while the other reaches down and back behind you, opening your chest along the diagonal between them, then swap - the raised arm sweeps down as the other rises.
3. Keep the arms long and the rhythm smooth and unhurried.
4. Each swap re-opens the chest along a new line, like slowly fanning a door back and forth on its hinge.
