Setup
- Kneel beside a flat bench or sit on the edge with your feet flat on the floor.
- Grasp a dumbbell with an underhand (supinated) grip, palms facing up.
- Rest your forearm on the bench so that your wrist and hand hang off the edge.
- Position your forearm perpendicular to the bench to ensure stability.
How to do it
- Inhale and slowly lower the dumbbell toward the floor by extending your wrist as far as comfortably possible.
- Exhale and curl the dumbbell upward by flexing your wrist, bringing the weight toward your body.
- Squeeze the forearm muscles at the top of the movement for a one-second pause.
- Lower the weight back to the starting position using a controlled 2-second eccentric tempo.
Form checklist
- Keep your forearm glued to the bench; do not let your elbow lift.
- Ensure the movement occurs only at the wrist joint.
- Maintain a firm grip on the dumbbell throughout the entire range of motion.
- Avoid using your legs or torso to generate momentum.
Pro tips
- At the bottom of the movement, allow the dumbbell to roll slightly down into your fingers to increase the range of motion and stretch the flexors.
- Focus on a slow, controlled eccentric phase to maximize time under tension, as forearms respond well to high-volume and high-tension work.
Make it harder
- Pause for 3 seconds at the peak contraction to intensify the burn.
- Perform the exercise with a 'thumbless' grip to further challenge your finger and wrist stability.
