The barbell wrist curl is a forearm isolation exercise that targets the wrist flexors on the underside of your forearms. With your forearms supported and palms facing up, you curl the bar through a small range of wrist flexion, making it a simple way to build forearm size and grip-supporting strength.
How to do the Barbell Wrist Curl
- 1Sit on a bench and rest your forearms on your thighs (or along the bench), palms facing up, with your wrists and hands hanging just past your knees.
- 2Hold the barbell with an underhand, shoulder-width grip so the bar sits across your fingers and lower palm.
- 3Keep your forearms pressed down and still — only your wrists should move during the set.
- 4Let the bar roll down toward your fingertips, opening your hands slightly to feel a stretch through the underside of your forearms.
- 5Curl the bar back up by closing your hands and flexing your wrists as high as they will go.
- 6Squeeze your forearms briefly at the top of the movement.
- 7Lower the bar slowly and under control back to the stretched position.
- 8Complete your reps, then set the bar down safely with control.
Form tips
- Use a full range of motion — let the bar roll to your fingertips at the bottom and flex fully at the top to work the wrist flexors through their whole range.
- Move slowly and deliberately, especially on the way down, so the muscles do the work instead of momentum.
- Keep your forearms firmly anchored on your thighs or the bench so the wrists are the only joints moving.
- Start light — the wrist flexors are small muscles, and lighter loads with strict form build them faster than heavy partial reps.
- Train forearms at the end of your session, since fatiguing your grip early can limit your other lifts.
Common mistakes
- Loading too much weight and only moving the bar a few inches, which turns the curl into a partial rep and shortchanges the wrist flexors.
- Lifting or rocking the elbows and arms to heave the bar up, which uses momentum instead of the forearms and reduces tension on the target muscle.
- Moving too fast and bouncing at the bottom, which relies on momentum and can strain the wrist instead of building it.
- Skipping the stretch at the bottom by not letting the bar roll into the fingers, which cuts the range of motion short.
- Holding the wrists rigid and lifting with the whole forearm, which removes the wrist flexion that makes this exercise work.
Frequently asked questions
What muscles does the barbell wrist curl work?
It isolates the wrist flexors — the muscles on the underside of your forearms that bend your wrist and curl your fingers toward your palm.
What's the difference between a wrist curl and a reverse wrist curl?
A wrist curl is done palms-up and trains the wrist flexors on the underside of the forearm. A reverse wrist curl is done palms-down and trains the muscles on the top of the forearm instead. They work opposite sides, so many lifters do both.
How many sets and reps should I do for forearms?
The wrist flexors respond well to higher reps. Try 2–4 sets of 12–20 reps with a controlled tempo and a full range of motion, resting briefly between sets.
Is the barbell wrist curl good for beginners?
Yes. It is a simple, low-skill isolation movement. Start with a light barbell, keep your forearms anchored, and focus on a full, controlled range of motion before adding weight.
