The rearward end of each of the levers is adapted to hold a removable weight while the forward end includes an angled handle adapted to be grasped and pulled in a downward direction by a person supported on the seat. The orientation of the sides of the frame, the levers and the handles with respect to the seat insures that pivotal movement of the levers occurs along vertical planes that diverge outwardly from the front of the seat, thereby providing a pulldown exercise that more naturally accommodates the musculoskeletal movements of a person.Other References
