The seated dumbbell palms-up wrist curl is a forearm isolation exercise performed on a bench with the forearms resting on the thighs, flexing the wrists to lift a dumbbell in each hand. The thighs take the elbow and shoulder out of the lift, and two dumbbells let each wrist move through its own range instead of being locked to a bar. With the hands past the knees, the handles roll to the fingertips at the bottom and load the finger flexors too. Lifters program it at the end of an arm or pull session forforearmsize and grip.
What Muscles Does the Seated Dumbbell Palms-Up Wrist Curl Work?
- Primary: Flexor carpi radialis, flexor carpi ulnaris (wrist flexors)
- Secondary: Flexor digitorum superficialis and profundus (finger flexors), palmaris longus
- Tertiary: Brachioradialis, pronator teres
How Do You Set Up for the Seated Dumbbell Palms-Up Wrist Curl?
Sit on the end of a flat bench with a dumbbell in each hand, feet flat and knees bent at about 90 degrees. Lean forward and lay the back of each forearm along the same-side thigh, palms up, so the wrists sit just past the kneecaps and the hands hang free. Rest the elbows on the thighs, keep the chest over the knees, and close the grip on both handles.
How Do You Perform the Seated Dumbbell Palms-Up Wrist Curl?
- Press the forearms into the thighs and let the wrists extend so the dumbbells drop toward the floor.
- Open the fingers slightly at the bottom, letting the handles roll down to the base of the fingers.
- Close the hands and curl the wrists up, lifting the dumbbells as high as the wrists will flex while the forearms stay glued to the thighs.
- Squeeze for one count at the top with the knuckles pointing at the ceiling.
- Lower the dumbbells slowly for a three-count until the wrists are fully extended below the knees again.
- Let the handles roll back to the fingers and reset the forearm contact before the next rep.
What Are the Key Form Cues?
- Forearms are bolted to the thighs: keep the whole forearm in contact from elbow to wrist on every rep, so the elbow never lifts to help.
- Roll the handle: let the dumbbell travel from the palm to the fingertips on the way down and back into the palm on the way up.
- Curl until the knuckles face the ceiling, not just until the hand is level with the forearm.
- Feel the burn along the inside of the forearm, not in the wrist joint itself.
- Lower slower than you lift, with the handles still in your hands at the bottom.
What Are the Most Common Mistakes?
- Grabbing dumbbells sized for a biceps curl: the elbows lift off the thighs and the arms curl the weight, so drop 5 pounds a hand until the forearms stay down.
- Cutting the bottom short: stopping with the hand level with the forearm skips the stretched half of the range, so let the wrists extend fully.
- Bouncing out of the bottom: a rapid drop into full extension loads the wrist ligaments at their end range, so lower on a count and pause before curling.
- Sitting too far back on the bench: the wrists end up over the thighs and the dumbbells hit the legs, so slide forward until the hands hang past the knees.
- Rounding the shoulders forward on every rep: the upper back sways as the weight lifts and the range shrinks, so keep the chest still over the knees.
What Are the Best Seated Dumbbell Palms-Up Wrist Curl Variations?
- Paused palms-up wrist curl: a lighter pair with a two-second top hold, for a lifter learning to keep the forearms down.
- Seated Palm Up Barbell Wrist Curl: a bar loads both wrists together and allows heavier weight.
- Dumbbell reverse wrist curl: palms down, working the wrist extensors instead.
- Seated one-arm dumbbell palms-up wrist curl: one hand at a time, so the free hand can hold the working forearm down.
- Seated palms-up low pulley wrist curl: a cable replaces the dumbbells and keeps tension at the bottom.
How Do You Progress the Seated Dumbbell Palms-Up Wrist Curl?
- Move up 5 pounds a hand once all sets reach the top of the rep range with the forearms still on the thighs.
- Build from 12 reps to 20 per set before each weight jump.
- Add a fourth set once three sets no longer leave the inside of the forearm pumped.
- Lower for a four-count, or hold the top squeeze for two seconds, before the next weight increase.
How Should You Program the Seated Dumbbell Palms-Up Wrist Curl?
Place the seated dumbbell palms-up wrist curl at the very end of an arm or pull session, after every curl and row that needs your grip, two to three times a week. Work 3 sets of 12 to 20 reps with 30 to 60 seconds of rest. Pair it with a reverse wrist curl so the extensors on the back of the forearm get matching work.
