Patent attributes
Improved designs for exercise machines that facilitate muscle development and other therapeutics are disclosed. The machine includes a frame, a pulley assembly, and cable extending through the pulley assembly. The cable has attachments, including an attachment for connecting to a pull handle. The cable is also connected to a selectively variable moveable resistance unit. This unit is structured to provide an elastic resistance when a pulling force is applied to the pull handle. The unit is connected to the cable and includes an elastomeric body that provides the elastic resistance and also includes an arc plate that provides a curved support member on which a portion of the elastomeric body at least partially wraps around. Movement of the arc plate causes the elastomeric body to stretch and to provide the elastic resistance.
