ABSTRACT:
A variable friction resistance exercise machine 10 including a pair of friction wheels 31 rotatably suspended by axles 30, 30' in a framework member 20. The axles 30, 30' are operatively connected to coiled lengths 41 of cable attached to one end to clutch rewind assemblies 40. The friction wheels 31 are provided with adjustable friction means 33, 35, 36, 37, and 38 to vary the frictional resistance required to rotate each friction wheel 30, 30' relative to the framework member 20.
