Reverse curls are an exercise that primarily work the arm muscles, including the biceps brachii and brachialis. The movement also enhances grip strength and builds forearm muscles, including the brachioradialis. The brachioradialis muscle is located on the front of the forearm and is responsible for flexing the elbow. By using a reverse grip, the biceps are less taxed, and more focus is on the brachioradialis. Reverse curls can be performed using dumbbells, straight bars, an EZ bar, cable attachments, and more. It is recommended to perform the exercise using an EZ curl bar for wrist comfort during the exercise. Wrist positioning is important when doing reverse curls, and it is recommended to focus on keeping tension in your wrists to keep a tighter grip throughout the movement.
