Set the cable machine to a low pulley with a straight or EZ-curl bar. Sit facing away, back straight, feet flat. Grasp the bar with an underhand grip, shoulder-width apart. Extend arms, feeling a biceps stretch. Curl the bar towards your shoulders, keeping upper arms still. Squeeze biceps at the top. Slowly lower with control. Repeat.
Keep elbows close to your sides. Avoid swinging; use controlled movements. Maintain a neutral wrist. Exhale on the curl, inhale on the lower. Adjust bench height for comfort.
