Rotate forearm, turning palm down (pronation), pause. Rotate back up, turning palm up (supination), pause. Repeat.
To isolate your forearm muscles, keep your upper arm stable and avoid any shoulder movement throughout the exercise, focusing the motion solely on your forearm rotation. Perform the rotation slowly and with controlled movements, resisting the urge to use momentum, which will ensure you engage the targeted muscles effectively and reduce the risk of injury. Maintain a neutral wrist position throughout the entire range of motion to prevent strain and ensure proper form. At the end of each repetition, consciously squeeze your forearm muscles to maximize muscle engagement and enhance the effectiveness of the exercise.
