ABSTRACT:
An exercise device provides resistance to flexion or extension of the arms or legs. The device is worn about the knee or elbow and has a first framework which is secured about the upper portion of the limb and a second framework which is secured about the lower portion of the limb. Struts protrude toward the joint from the upper framework and from the lower framework, and are connected at the joint by a resistive pivot connection. The resistive pivot connection has a resistive mechanism which is attached between the struts by matching projections and conduits which are on opposing faces of the struts and ends of the mechanism. The degree of resistance is varied by substituting a mechanism, which is made of an elastomeric material, with another of different resistive properties. Resistance may be varied by changing the positions of the projections and conduits relative to each other. Moving the relative positions of the conduits and projections would also change the muscle group being exercised. Alternatively, the resistive pivot connection can use a linear resistance such as a shock absorber between the frameworks.
