Exercise Advice: This exercise is similar to the reverse barbell curl exercise except that you will be using a short bar attached to a pulley machine. Stand with your feet about shoulder width apart and grab a short bar attached to a pulley machine with both hands, palms down. Begin with your arms hanging down, fully extended. Curl the bar up to a level that is parallel to the floor. Be sure to keep your elbows locked in place throughout the movement and to focus on having your forearms do the work.
