Setup
- Stand tall with your feet shoulder-width apart and your core engaged.
- Extend both arms straight out in front of you at shoulder height, palms facing the floor.
- Spread your fingers as wide as possible to create tension across the hand.
How to do it
- Rapidly curl your fingers halfway toward your palm and then 'flick' them back out to full extension with speed.
- Maintain a fast, rhythmic 'bouncing' tempo, focusing on the quickness of the finger extension.
- Breathe rhythmically and continuously, avoiding holding your breath as the forearm pump increases.
- 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.
