Before the first rep
How to set up
- 01
Load light. Use an empty or lightly loaded bar, with collars on so the plates cannot slide when the bar tilts. Your wrists are small joints and the range is short, so this lift needs far less weight than any curl.
- 02
Sit at the end of a bench. Sit with your feet flat and about hip width apart, knees bent to roughly 90 degrees, so your thighs make a level shelf.
- 03
Forearms on thighs. Lay your forearms along your thighs, palms facing up, so your wrists hang just past your knees and can bend freely.
- 04
Grip. Hold the bar with an underhand grip, hands about shoulder width or a little narrower, thumbs around the bar.
- 05
Lean in. Lean your torso forward a little so your forearms stay pinned to your thighs for the whole set.
Step by step
How to do the barbell wrist curl
- 01
Start at the top. Begin with your wrists curled up and the bar in your palms. Your forearms stay flat on your thighs.
- 02
Lower with the wrists. Slowly let your wrists bend back so the bar moves down toward the floor. Only your hands move.
- 03
Let it roll. At the bottom, open your fingers a little so the bar rolls down toward your fingertips. Keep it under control and never let it slip off.
- 04
Close the hand. Curl your fingers back around the bar, rolling it into your palm.
- 05
Curl the wrists up. Bend your wrists up as high as they go without lifting your forearms off your thighs. Pause for a moment, then start the next rep.

Fix these first
Common mistakes
Going too heavy
Drop the weight until you can do clean, full reps. Heavy wrist curls turn into short, jerky reps and strain the wrist and elbow.
Forearms lifting off the thighs
Keep your forearms pinned and lean in. If your elbows start to rise, your biceps and shoulders are doing the lifting.
Bouncing out of the bottom
Lower slowly and pause briefly before closing your hand. A bounce takes the load off at the bottom and jars the wrist.
Half reps
Use the whole range: wrist bent back and bar at your fingers at the bottom, wrist curled fully up at the top.
Rushing the set
Take about two seconds down and one up. The muscles are small, so control matters more than speed.
Stay safe
Start lighter than you think and add weight in small steps, because wrists and elbows take time to adapt. Put collars on the bar, and on a wrist roller make sure the plate is clipped or tied on securely and your feet are clear of it. To end a set you cannot finish, curl the bar back up and rest it on your thighs or set it on the floor in front of you; do not let it roll out of your fingers. Stop if you feel sharp pain in the wrist or the inside of the elbow, or numbness or tingling in your fingers, and get it checked by a physio or doctor if it does not settle.
Programming
Sets, reps and how much weight
| Goal | Sets | Reps | Load | Rest |
|---|---|---|---|---|
| Muscle | 2 to 4 | 10 to 15 | 60–72% 1RM | 1 to 1.5 min |
| Endurance | 2 to 3 | 15 to 25 | 45–60% 1RM | 45 to 60 sec |
| Technique | 2 to 3 | 12 to 15 | 40–55% 1RM | 1 min |
Plan your next session
Put in a recent set. You get working weights for your goal, a warm-up and the plates to load.
Estimated 1RM 216 lb
Endurance sets
95–130lb
2 to 3 sets of 15 to 25 reps, 45 to 60 sec rest. Lighter and longer sets. A strong burn in the forearm is normal; sharp pain is not.
Warm up to 115 lb
Tap a set to see its plates.

Estimates use the Epley formula and work best from sets of 3 to 8 reps. Treat them as a starting point and adjust by how the first working set moves.
Questions
Barbell Wrist Curl questions
What muscles do wrist curls work?
Wrist curls work the wrist flexors on the palm side of the forearm. Letting the bar roll to your fingertips also works the finger flexors that close your hand.
What is the difference between a wrist curl and a reverse wrist curl?
A wrist curl is done palms up and trains the flexors on the inside of the forearm. A reverse wrist curl is done palms down and trains the extensors on the back of the forearm, which are weaker, so use a lighter bar.
How do you use a wrist roller?
Hold the roller at shoulder height with straight arms and an overhand grip, turn it hand over hand to wind the weight up, then unwind it slowly back down. Rolling the top of the handle toward you works the extensors on the back of the forearm; rolling it away from you works the flexors on the palm side.
Do wrist curls improve grip strength?
They help, especially if you let the bar roll to your fingers and close your hand on every rep. Heavy holds and carries tend to build crushing grip more directly, so many programs use both.
How many sets and reps of wrist curls should I do?
Two to four sets of 10 to 15 reps, two or three times a week, suits most people. Forearms recover quickly, but add volume slowly if your elbows or wrists get sore.
Should I do wrist curls seated or standing?
Seated with your forearms on your thighs is the standard version because it stops your arms from helping. You can also stand holding the bar behind your thighs, palms facing back, and curl your wrists up from there, but the seated version is easier to keep strict.
