Abstract
An exercising device for use in strengthening, conditioning and rehabilitating body joints such as the knee and shoulder. The device is used in connection with conventional exercising apparatus to minimize detrimental shearing forces on the joint during the exercise procedures. This is accomplished by replacing the conventional single contact pad on the limb with two contact pads or pad and handgrip mounted on a variable fulcrum that will produce the desired counterforce to the shearing force on the joint.
