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.
