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 represents how much force can be produced at specific joint angles. An  ascending strength curve exists when you can display more force as you extend the joints; exercises such as deadlifts, squats, bench presses and military presses have ascending strength curves. Chains would be valuable for these exercises because the increasing resistance during the strongest joint angles would make the exercise feel  smooth through the entire movement.<BR>A descending strength curve exists when you can display more force as you flex a joint. An adductor (inner thigh) pull with cables or a machine would have a descending strength curve, as you can display more force when the legs are closest together. Some exercises have ascending-descending strength curves, which means that you can display more strength at the mid-range of the movement. Chins and standing biceps cur
