1. 1

   Stand beside a door frame with the forearm on it at about shoulder height.

2. 2

   Keep the body upright with the chest open.

3. 3

   Step forward slightly with the foot on the same side, letting the body drift forward.

4. 4

   Pause at a gentle stretch across the chest, then slowly return to the start.

Tip: Use the door frame to anchor the arm and lean forward slowly; aim for a gentle stretch, never into pain.
