How to do it

Hold your arms out in front of you and rapidly open and close your hands, spreading the fingers wide then clenching into a fist. Move quickly and continuously to build endurance and blood flow through the hands and forearms. Keep the wrists steady and let the fingers do the work.

  1. 1Forearm muscles working as you open and clench the hands
  2. 2A full spread of the fingers, then a firm squeeze into a fist
  3. 3A steady pump building through the hands and forearms

Common mistakes

  • Don't let the wrists flop; keep them steady and neutral
  • Avoid tensing the shoulders; keep the work in the hands
  • Don't go so fast that the range of the fingers shrinks
