How to perform Two-Arm Dumbbell Preacher Curl
- Grab a dumbbell with each arm and place the upper arms on top of the preacher bench or the incline bench. The dumbbell should be held at shoulder length. This will be your starting position.
- As you breathe in, slowly lower the dumbbells until your upper arm is extended and the biceps is fully stretched.
- As you exhale, use the biceps to curl the weights up until your biceps is fully contracted and the dumbbells are at shoulder height.
- Squeeze the biceps hard for a second at the contracted position and 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.
- Warm up the pattern with a couple of lighter, submaximal sets before your working sets.
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.
