Start: Attach the rope handle or EZ-curl bar to the high pulley. Stand with your back to the weight stack, about a foot or two in front of it, and reach back to grab the attachment. Bend over at the hips until your torso and upper arms are parallel to the floor. Your upper arms should be next to your ears, with your elbows bent 90 degrees and the attachment just above the back of your head.
Finish: Straighten your arms. Pause, then return to the starting position.
