Bulging biceps and triceps are yours to develop with this intelligent dual-function design. Raise or lower the adjustable seat for proper positioning and then rest your arms on the over-stuffed support pad. Positioned at a 30 angle for precise biomechanical movement, the thoughtful combination of 2in x 2in and 2in x 4in supportive steel blends structural integrity with comfort. Pull the jumbo pop pin to lower the lifting arm and grab hold of the rotating v-bar handle to blast out a burning set of arm curls. Now adjust the lifting arm upward and lock it in for an exhilarating triceps workout. Once again, body-solid brings you two functions for the price of one.
