- Beginner

Setup
- Kneel on the floor facing the long side of a flat bench.
- Grasp a barbell with a shoulder-width, underhand (palms up) grip.
- Rest your forearms on the bench so your wrists hang approximately 2-3 inches over the edge.
- Shift your weight forward so your forearms are firmly pressed against the padding.
How to do it
- Inhale and slowly lower the barbell by extending your wrists toward the floor, allowing the bar to roll down into your fingers for a full stretch.
- Exhale as you curl the barbell upward by flexing your wrists, bringing the palms toward your inner forearms.
- Squeeze the forearms 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 forearms glued to the bench; do not let your elbows lift.
- Ensure the movement occurs only at the wrist joint, not the elbows or shoulders.
- Avoid using momentum or 'swinging' the weight up.
- Maintain a full range of motion, from a deep stretch to a full contraction.
Pro tips
- To maximize muscle fiber recruitment, allow the bar to roll all the way to your distal phalanges (fingertips) at the bottom before curling back up.
- Focus on the mind-muscle connection by visualizing your forearm muscles shortening as you lift the bar.
Make it harder
- Perform the exercise with a thumbless grip to increase the challenge on the finger flexors.
- Add a 3-second isometric hold at the peak of the contraction to increase time under tension.
