Palms-Up Dumbbell Wrist Curl Over A Bench
This dumbbell version of the palms-up wrist curl trains the forearm flexors, the muscles on the underside of the forearm that close your hand and grip a bar. You rest your forearms on a bench with your palms up, then curl the dumbbells using only your wrists. Working one dumbbell in each hand lets each wrist move through its own comfortable range, which makes this a good entry point before progressing to a barbell.
Why it works
With your forearms braced against the bench, your elbows can't help lift the weight, so the flexor muscles on the underside of the forearm are the ones doing the curling. Those muscles are the same ones that keep your hand closed around a bar during a heavy pull, so training them directly builds the kind of grip endurance that carries over to deadlifts and rows. Using dumbbells rather than a barbell lets a weaker wrist move independently instead of being forced to match a stronger one, which is useful early on or when one side lags behind.
Set up
- Sit on the edge of a bench holding a dumbbell in each hand, palms facing up.
- Rest your forearms on your thighs or the bench, wrists hanging just past your knees.
- Let the dumbbells settle low, toward your fingertips, before you start.
How to do it
- Begin with your wrists extended and the dumbbells resting low, near your fingertips.
- Curl the dumbbells upward by closing your fingers, then flexing your wrists.
- Lift until your wrists are fully curled, squeezing briefly at the top.
- Lower the dumbbells slowly back down.
- Let your wrists extend again at the bottom so the dumbbells roll toward your fingertips.
- Keep your forearms pinned to the bench or your thighs the entire set.
Form cues
- Forearms stay still on the bench or thighs, only the wrist bends.
- Let the dumbbells roll toward the fingers at the bottom for a full range.
- Squeeze hard at the top of every rep.
- Lower under control instead of letting gravity do it.
Breathing: Exhale as you curl the dumbbells up, inhale as you lower them back down.
Common mistakes
Letting the elbows bend to help lift the weight.
Fix: Keep your forearms flat against the bench or your thighs so the elbow stays locked out of the movement.
Cutting the range short at the bottom instead of letting the wrist fully extend.
Fix: Allow the dumbbells to roll down toward your fingertips at the bottom of every rep before curling back up.
Choosing dumbbells too heavy to control through a full, slow range.
Fix: Drop the weight until you can complete each rep with a controlled tempo in both directions.
How to program it
- This is light, single-joint work, so two or three times a week is a comfortable frequency for most people without cutting into recovery from bigger lifts.
- A rep range of 12 to 15 per arm across two or three sets suits the forearm flexors well; they respond better to volume than to heavy singles.
- Fit it in near the end of a pulling or arm-focused session, once your grip has already been challenged by heavier lifts.
Safety notes
- If you notice sharp pain in the wrist or forearm rather than the usual muscle burn, stop the set and reduce the load.
- Warm the wrists up with a light set before loading up, since tendons around a small joint like the wrist need more time to adapt than larger muscles.

Frequently asked questions
How many sets and reps of dumbbell wrist curls should I do?
Two or three sets of 12 to 15 reps per arm works well for most people. Focus on a full range of motion before adding weight.
Which wrist curl should I start with, dumbbell or barbell?
Start with dumbbells. They let each wrist move independently, which is more forgiving while you're still building coordination and identifying if one side is weaker.
Can I do palms-up wrist curls standing instead of seated?
It's harder to keep the forearms fully still while standing, so seated with your forearms braced on a bench or your thighs gives you better isolation and control.
Why does my grip feel weak by the end of a workout even though I train forearms?
Most pulling exercises tax the flexor grip heavily before you ever isolate it directly. Doing wrist curls at the end of a session, not the start, avoids pre-fatiguing the grip you need for your main lifts.
