How to do the 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
The prime mover is the biceps brachii, which bends the elbow and rotates the forearm palm-up.
Even with a single joint doing the moving, the muscle is not working alone — the forearms hold the grip, which is often what gives out first.
How this movement works
One joint changes angle and the resistance travels toward you along a single arc. Nothing is positioned to help, so tension stays where you aimed it and the usable load drops sharply against a multi-joint pull for the same muscle. Protect the range of motion; buying weight by shortening the arc defeats the point.
It is filed under strength: produce force against resistance for a countable number of repetitions, and progress the resistance over time.
What you need
Dumbbells let each side work on its own, surfacing a strength difference between limbs that a barbell would quietly cover for, and leaving the wrist free to rotate through the movement.

Difficulty
Listed at intermediate level. It assumes you already own the underlying pattern and can hold position under load — if the position breaks before the target muscle tires, drop back to a beginner variation until it does not.
