How to do it

1. Stand tall and raise your fists up in front of your face, elbows lifted.
2. Roll your fists around each other in small, quick circles, as if working an invisible speed bag hanging just above eye level.
3. Keep the circles tight and the rhythm continuous.
4. The bag may be imaginary but the shoulder burn is entirely real - keeping those elbows up is where this earns its place.
