Abstract:
1. A treadmill comprising: a frame; an endless belt supported on said frame; a support surface, said endless belt passing over said support surface; an arm member being displaceable forwardly and rearwardly relative to the frame by a reciprocating arm movement of a user, said displacement providing a principal motivation force for imparting motion to rotate said endless belt in a first direction; a drive roller coupled to said belt for imparting motion to said belt; a transmission system linking said drive roller to said displaceable arm member; and a motor assist device coupled to said endless belt, wherein operation of said motor assist device will impart an assisting motivation force to rotate the endless belt in said first direction; and wherein said assisting motivation force alone is insufficient to power said endless belt when the user is on said endless belt.
