Stand facing the sled and grasp the handles with an underhand grip. Keep your elbows close to your body and your core braced. Curl the sled toward your chest by bending your elbows while keeping your upper arms mostly fixed. Pause briefly at the top and squeeze your biceps, then slowly lower the sled back to the starting position under control. Avoid using momentum and maintain steady tension throughout the movement.
