Herz explained in his patent how his  cam would achieve this:  . . . in working with such apparatuses, during the whole movement, the muscles shall be exerted in accordance with their momentary tension or pulling force. This meant there would be no sticking points so the muscles would be working hard throughout the entire lift.<BR>A strength curve is a mathematical model that represens how much force can be produced at specific joint angles. An  ascending strength curve exists when you can display more force as you
