Setup

  1. Stand tall with your feet shoulder-width apart and your core engaged.
  2. Extend both arms straight out in front of you at shoulder height, palms facing the floor.
  3. Spread your fingers as wide as possible to create tension across the hand.

How to do it

  1. Rapidly curl your fingers halfway toward your palm and then 'flick' them back out to full extension with speed.
  2. Maintain a fast, rhythmic 'bouncing' tempo, focusing on the quickness of the finger extension.
  3. Breathe rhythmically and continuously, avoiding holding your breath as the forearm pump increases.
  4. Continue the movement for the duration of the set, ensuring fingers reach full extension on every rep.

Form checklist

  • Keep your arms fully locked at the elbows to isolate the forearms.
  • Ensure your shoulders remain down and relaxed, not shrugging toward your ears.
  • Maintain a neutral wrist position; do not let the wrists collapse or bend excessively.
  • Focus on the 'flick' at the end of the extension to maximize extensor activation.

Pro tips

  • Visualize flicking water off your fingertips as fast as possible to increase the intensity of the contraction.
  • To maximize the pump, try to increase the speed of the bounces as the muscles begin to fatigue.

Make it harder

  • Perform the exercise with your arms extended directly overhead to add a postural and shoulder stability challenge.
  • Vary the hand orientation by rotating your palms to face upward or toward each other mid-set.
