Zottman Curl
How to Do Zottman Curl With Proper Form
Begin standing with dumbbells and palms forward.
Curl upward with the supinated grip.
Keep upper arms mostly fixed.
At the top rotate the forearms until palms face down.
Lower slowly with the pronated grip.
Reach full comfortable elbow extension.
Rotate back to palms up before the next rep.
Form Check & Technique
DO THIS (Technique Tips)
- Use less weight than normal curls
- Finish the supinated curl first
- Rotate at the top
- Lower slowly palms down

- Too much weight
- Wrists collapsing
- Torso swinging

- Forgetting to reset palms up
About Zottman Curl
The Zottman curl combines a palms-up supinated concentric with a palms-down pronated eccentric. The grip transition at the top is the defining feature.
Zottman Curl Muscles Worked
The lifting phase uses a supinated curl while the lowering phase uses pronation.
- Grip changes alter mechanics, but the Zottman curl is not proven superior for total arm hypertrophy.

Why the Grip Changes at the Top
The top rotation separates the palms-up concentric from the palms-down eccentric.
Supinated Up, Pronated Down
Complete the curl before rotating if you want the classic Zottman pattern.
Zottman vs Reverse Curl
Reverse curls are pronated in both directions; Zottman curls are supinated up and pronated down.
Zottman vs Hammer Curl
Hammer curls stay neutral throughout; Zottman curls change grip.
Why the Eccentric Matters
The pronated lowering phase is part of the exercise identity, so do not rush it.
