How to perform Alternate Incline Dumbbell Curl
- Sit down on an incline bench with a dumbbell in each hand being held at arms length. Tip: Keep the elbows close to the torso.This will be your starting position.
- While holding the upper arm stationary, curl the right weight forward while contracting the biceps as you breathe out. As you do so, rotate the hand so that the palm is facing up. Continue the movement until your biceps is fully contracted and the dumbbells are at shoulder level. Hold the contracted position for a second as you squeeze the biceps. Tip: Only the forearms should move.
- Slowly begin to bring the dumbbell back to starting position as your breathe in.
- Repeat the movement with the left hand. This equals one repetition.
- Continue alternating in this manner for the recommended amount of repetitions.
Muscles worked
- Biceps (primary): bends the elbow and turns the palm up during pulls and curls.
- Forearms (secondary): controls your grip and keeps the wrist steady under load.
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.
