Dumbbell Wrist Curl

A small-range curl where you flex the wrist with a dumbbell while your forearm rests on your thigh or a bench. It isolates the forearm flexors on the palm side of the forearm. Useful for lifters who want bigger forearms or more grip endurance.

Muscles worked

  • Forearms

The forearm flexors bend the wrist and close the fingers. Letting the dumbbell roll down to the fingertips adds finger-flexor work.

How to set up

  1. Sit on a bench holding a dumbbell with a palm-up grip.
  2. Rest your forearm on your thigh or the bench, wrist just past the edge.
  3. Let the wrist hang back with the weight.
  4. Keep the forearm fixed in place.

How to do each rep

  1. Curl the wrist up as far as you can.
  2. Squeeze briefly at the top.
  3. Lower slowly until the wrist is fully extended.
  4. Optionally let the dumbbell roll to your fingertips and curl it back.

Common dumbbell wrist curl mistakes

Lifting the forearm

Keep the forearm pinned so only the wrist moves.

Going too heavy

Use light weights and higher reps for a full range of motion.

Bouncing at the bottom

Lower under control and pause before curling up again.

Sets, reps, and progression

Surpass starts the dumbbell wrist curl at 12–20 reps with about 1 reps in reserve. As an isolation exercise it fits well after your main compound lifts.

Use 15-25 rep sets and add weight in small jumps. Add reverse wrist curls to balance the forearm extensors.

Questions

Do wrist curls build forearm size?

Yes. They target the flexors on the palm side of the forearm, which make up much of its bulk. High reps with a full range work best.

Wrist curls vs. hammer curls for forearms?

Wrist curls train the flexors on the inside of the forearm, while hammer curls hit the brachioradialis on top. Doing both covers the forearm well.
