How to perform Zottman Curl
- Stand up with your torso upright and a dumbbell in each hand being held at arms length. The elbows should be close to the torso.
- Make sure the palms of the hands are facing each other. This will be your starting position.
- While holding the upper arm stationary, curl the weights while contracting the biceps as you breathe out. Only the forearms should move. Your wrist should rotate so that you have a supinated (palms up) grip. 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.
- Now during the contracted position, rotate your wrist until you now have a pronated (palms facing down) grip with the thumb at a higher position than the pinky.
- Slowly begin to bring the dumbbells back down using the pronated grip.
- As the dumbbells close your thighs, start rotating the wrist so that you go back to a neutral (palms facing your body) grip.
- Repeat 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.
