- Grasp bar with shoulder width underhand grip.
- With elbows to side, raise bar until forearms are vertical.
Lower until arms are fully extended. Repeat.
- 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 with straight barbell.
Movement with cambered bar as shown above is also known as EZ
Barbell Curl or EZ Bar Curl. Also see mechanical
analysis of arm curl.
