Setup
- Stand or sit upright with your arms extended straight out in front of you at shoulder height.
- Clench your hands into the tightest fists possible, wrapping your thumbs over your fingers.
- Position your palms facing downward toward the floor.
How to do it
- While maintaining a maximum-effort squeeze in your fists, slowly hinge your wrists upward as high as possible.
- Exhale during the upward movement and hold the peak contraction for one second.
- Slowly lower your fists back to the starting position and then continue into a downward curl as far as your range of motion allows.
- Inhale as you return to the neutral starting position, maintaining a controlled 2-second tempo for each phase.
Form checklist
- Keep your arms fully locked at the elbows to isolate the forearm muscles.
- Maintain a maximum-intensity squeeze in your fists throughout the entire set.
- Ensure the movement occurs strictly at the wrist joint, avoiding any shoulder shrugging.
- Move through the largest range of motion possible in both directions.
Pro tips
- Focus on the mind-muscle connection by imagining you are trying to crush a small stone inside your palm.
- To increase intensity, perform the movement until you reach a significant 'burn' or local muscular fatigue.
Make it harder
- Perform the exercise with your arms extended out to your sides (T-pose) to introduce a shoulder stability challenge.
- Add a 'pulse' at the top and bottom of the range of motion to increase time under tension.
