Instructions
Preparation
Face low pulley and grasp stirrup cable attachment to one side with an underhand grip.
Execution
With elbow to the side, raise bar until forearms are vertical. Lower until arms are fully extended. Repeat. Continue with opposite arm.
Comments
An alternative method is to stand facing with side of exercise arm toward low pulley. When elbows are fully flexed, elbows should only travel forward slightly allowing forearms to be no more than vertical. This can allow for a relative release of tension in muscles between repetitions.
