How to Do the Wrist Curl

The wrist curl is a small isolation move that works the forearm flexors, the muscles on the underside of your forearm that close your hand and bend your wrist. It is a simple way to build forearm size and improve your grip on rows, pull-ups and deadlifts. Beginners can use it with very light loads.

    Sit on a bench holding a dumbbell or barbell with palms facing up.

    Let the weight roll down toward your fingertips, keeping a firm grip.

  4. 4

    Curl your hands up toward your forearms as far as you can.

  5. 5

    Pause briefly at the top and squeeze your forearms.

Common mistakes

Lifting the forearms off the thighs

Keep your forearms anchored so only the wrists move.

Using too much weight

Choose a load that lets you use full range without jerking.

Rushing the lowering phase

Take two to three seconds to lower so the forearm works through the stretch.

Cutting the range short

Let the bar roll to your fingertips, then curl up fully.

Sets and reps

Muscle growth3 sets of 12–20 reps, 60 sec rest
Endurance2–3 sets of 20–30 reps, 45 sec rest

Forearm tendons are easy to irritate, so keep the load light and add reps before weight; stop if you feel sharp wrist or elbow pain.

Wrist Curl FAQ

How many reps should I do for wrist curls?

The forearms respond well to higher reps, usually 12–20 per set, because they are used for endurance all day. Choose a weight where the last few reps feel hard but your form stays strict.

Are wrist curls worth doing?

If you want bigger forearms or your grip limits your lifts, they help. Heavy rows and deadlifts already train the forearms, so a couple of sets once or twice a week is enough.

Barbell or dumbbell for wrist curls?

Dumbbells let each wrist move through its own range and expose strength differences between sides. A barbell lets you load a little heavier and is easier to set up.
