The dumbbell standing back wrist curl is an isolation exercise for the forearms, specifically the muscles along the back of the forearm that extend the wrist. Performed standing with the dumbbells held at your sides and your palms facing back, it strengthens grip support, builds forearm thickness, and helps balance the more commonly trained wrist flexors.
How to do the Dumbbell Standing Back Wrist Curl
- 1Stand tall with a dumbbell in each hand, arms hanging straight down at your sides and feet about shoulder-width apart.
- 2Rotate your forearms so your palms face backward (pronated grip), with the dumbbells resting just behind your thighs.
- 3Keep your upper arms and elbows locked against your sides so only your wrists move.
- 4Curl the dumbbells upward by extending your wrists, lifting the backs of your hands toward your forearms.
- 5Pause briefly at the top, squeezing the muscles on the back of your forearms.
- 6Lower the dumbbells under control until your wrists are fully flexed and you feel a stretch along the top of your forearms.
- 7Complete your reps, then set the dumbbells down with control.
Form tips
- Move only at the wrist joint — keep your elbows and shoulders still so the forearm extensors do the work.
- Use a controlled tempo and a full range of motion rather than swinging the dumbbells with momentum.
- Start lighter than you would for a standard wrist curl; the extensors are smaller and fatigue quickly.
- Hold the top contraction for a beat each rep to maximize tension on the back of the forearm.
Common mistakes
- Using too much weight, which forces you to swing from the elbows or shoulders and takes tension off the forearm extensors.
- Cutting the range of motion short, so the muscles never fully lengthen or contract and growth stalls.
- Letting the elbows drift or bend, which turns the movement into a partial curl instead of isolating the wrists.
- Gripping so tightly that the wrist flexors take over, defeating the purpose of training the back of the forearm.
Frequently asked questions
What muscles does the dumbbell standing back wrist curl work?
It targets the forearms — specifically the wrist extensor muscles on the back of the forearm that lift the back of the hand toward you. It is the reverse of a standard wrist curl, which trains the flexors on the underside.
What is the difference between a back wrist curl and a regular wrist curl?
A back (reverse) wrist curl is done with palms facing back and extends the wrist to work the forearm extensors. A regular wrist curl uses a palms-up grip and flexes the wrist to work the forearm flexors. Training both balances the forearm.
Is the dumbbell standing back wrist curl good for beginners?
Yes. It is a simple isolation movement with a low injury risk. Beginners should start with very light dumbbells, focus on moving only at the wrist, and use a full, controlled range of motion.
How many sets and reps should I do?
Because the forearm extensors are small and respond well to volume, aim for 2 to 4 sets of 12 to 20 reps with light to moderate dumbbells, resting briefly between sets.
