How to do it
Stand in a short split stance with the knees soft and the trunk tall.
Swing the arms from the shoulders with the elbows at about 90°: hands to chin height in front, hands past the hips behind.
Speed up for the last few seconds without letting the shoulders rise.
Tips
Relaxed hands and face.
The arms swing forward and back, not across the body.
