How to perform Seated Dumbbell Curl
- Sit on a flat bench with a dumbbell on each hand being held at arms length. The elbows should be close to the torso.
- Rotate the palms of the hands so that they are facing your torso. This will be your starting position.
- While holding the upper arm stationary, curl the weights and start twisting the wrists once the dumbbells pass your thighs so that the palms of your hands face forward at the end of the movement. Make sure that you contract the biceps as you breathe out and make sure that only the forearms move. Continue the movement until your biceps are fully contracted and the dumbbells are at shoulder level. Hold the contracted position for a second as you squeeze the biceps.
- Slowly begin to bring the dumbbells back to the starting position as your breathe in and as you rotate the wrists back to a neutral grip.
- Repeat for the recommended amount of repetitions.
Muscles worked
- Biceps (primary): bends the elbow and turns the palm up during pulls and curls.
Sets & reps by goal
| Goal | Sets × reps | Load | Rest |
|---|---|---|---|
| Strength | 3–5 × 3–5 | Heavy (~85%+) | 2–3 min |
| Hypertrophy | 3–4 × 8–12 | Moderate (~65–75%) | 60–90 s |
| Endurance | 2–3 × 15–20 | Lighter (~50–60%) | 30–45 s |
Pick the row that matches your goal. If you're newer, anchor in the hypertrophy range while you groove the form.
Form tips
- Keep the upper arm still and pinned to your side so the movement happens only at the elbow.
- Each side works on its own, so match the depth and speed of both arms and don't let the stronger side take over.
- Treat every rep the same — a repeatable setup and bar path is what lets you add weight safely over time.
- Stop a rep or two short of failure on most sets to keep form clean and recover faster.
Common mistakes
- Swinging the torso to fling the weight up instead of actually curling it.
- Letting the dumbbells drift apart or clang together at the top instead of controlling the path.
- Chasing weight jumps before the current load feels solid on every rep.
