The Zottman Curl is a smart and effective arm exercise that trains both the biceps and forearms in one movement. By curling the weight up with a supinated grip and lowering it with a pronated grip, you increase time under tension and strengthen the muscles around the elbow. If you want stronger arms with better grip and forearm development, the Zottman Curl deserves a place in your training.


🎥 How to Perform the Zottman Curl




💪 Muscles Worked in the Zottman Curl


  • Biceps (long and short head)

  • Brachialis

  • Brachioradialis (forearms)

  • Wrist flexors and extensors


🏋️ Step-by-Step Instructions


  1. Stand tall with dumbbells by your sides, palms facing forward.

  2. Curl the dumbbells up under control.

  3. Rotate your wrists at the top so palms face down.

  4. Lower the dumbbells slowly with control.

  5. Rotate wrists back to palms up at the bottom.

  6. Repeat for the desired reps.
