Barbell Wrist Curl

The barbell wrist curl is a forearm isolation exercise: with your forearms resting palms-up on your thighs or a bench, you curl a barbell up by bending your wrists. It works the wrist and finger flexors on the inside of the forearm, the muscles that drive grip.

How to do it

Step by step

  1. Sit at the end of a bench and rest your forearms along your thighs or the bench, palms facing up, with your wrists and hands just past your knees or the edge.
  2. Hold the bar with an underhand grip at about shoulder width.
  3. Press your forearms down so only your wrists can move.
  4. Let your wrists bend back under control so the bar travels down. If you choose, let it roll towards your fingertips for a deeper stretch.
  5. Close your fingers around the bar, then curl your wrists up as high as they travel. Squeeze briefly at the top.
  6. Bring the bar back down slowly to the stretched bottom and start the next rep.
  7. After the last rep, set the bar down on the bench or the floor.

Common faults

What goes wrong, and the fix

Forearms lifting

Fix: Press your forearms into your thighs or the bench so only your wrists move.

Bouncing out of the stretch

Fix: Bring the bar down under control and pause briefly before curling.

Short half-reps

Fix: Work from a full stretch at the bottom to a full curl at the top.

Rolling the bar too far

Fix: Let the bar roll only as far as your fingers can still curl it back.

Programming

What the research says

Muscle growth · first choiceRehab & prehabGeneral fitnessSport performanceEndurance

  • Load and reps — Research comparing loads finds muscle growth is similar across a wide range of loads when sets are taken close to failure, and lighter loads favour muscular endurance. Moderate loads and higher reps are common for the forearms.
  • Effort — Studies show sets that finish a few reps short of failure capture most of the growth benefit; true failure adds only a small extra effect.
  • Volume — Research links more weekly sets for a muscle to more growth, with diminishing returns. Gripping in rows, deadlifts and carries also works the forearm flexors, and counting such indirect work improves volume estimates.
  • The evidence gap — There is little direct research on wrist-curl training for strength or size, so programming draws on research from other muscles.
