Dumbbell Wrist Curl
A seated wrist curl for the forearm flexors that builds wrist strength and forearm thickness — a small accessory every arm day needs.
How to do it
- Sit on a bench and rest your forearm along the top of it, palm up, with your wrist hanging just past the edge.
- Hold the dumbbell with a relaxed grip and let it roll down to your fingertips at the bottom.
- Close your fingers and curl your wrist, lifting the dumbbell only by bending at the wrist while your forearm stays pressed to the bench.
- Squeeze hard at the top with the wrist fully flexed and hold the contraction for a short count.
- Lower the dumbbell slowly over 2–3 seconds to full wrist extension at the bottom.
- Do 12–20 reps, then switch arms and do the same number on the other side.
Key technique cue
Forearm stays on the bench; bend the wrist, not the elbow, and roll to the fingers.
Common mistakes
- ✕ Lifting the forearm off the bench, which turns the rep into an elbow curl and takes the load off the forearm.
- ✕ Going too heavy and barely moving the wrist, which cuts the working range in half.
- ✕ Skipping the phase where the dumbbell rolls into the fingers, which leaves out the deepest grip and forearm work.
- ✕ Lowering too fast instead of under control, when the lowering is exactly what drives most forearm growth.
Benefits
- ✓ Builds forearm flexor thickness and visible lower-arm size.
- ✓ Strengthens the grip for pulls, presses and carries.
- ✓ Reinforces wrist control and tendon resilience under load.

About the exercise
The Dumbbell Wrist Curl is the most direct way to train the forearm flexors. Sitting with your forearm resting on a bench, palm up, you let the dumbbell roll down to your fingers and then curl it back up using only the wrist. It is a small isolation movement that builds grip strength and the muscle on the underside of the forearm. Wrist curls are a basic accessory exercise. They round out arm days, support grip work for pulling and strength programs, and often sit next to curls and extensions in hypertrophy blocks.
