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. Clench your fists as tight as you can, squeezing hard for a moment, then snap your hands open, spreading the fingers as wide as they'll go.
  3. Keep alternating - clench, spread, clench, spread - while your arms stay up and level.
  4. It looks like nothing; by the end of a long set your forearms will disagree.
