Instructions

  1. Preparation: Grasp bar with shoulder width underhand grip. Execution: With elbows to side, raise bar until forearms are vertical. Lower until arms are fully extended. Repeat. Comments: When elbows are fully flexed, they can travel forward slightly allowing forearms to be no more than vertical. This additional movement allows for relative release of tension in muscles between repetitions. Exercise can also be performed withstraight barbell. Movement with cambered bar as shown above is also known as EZ Barbell Curl or EZ Bar Curl. Also seemechanical analysis of arm curlandquestion regarding elbow position.
