Abstract
A motorless manually operated treadmill exerciser including a frame structure having a plurality of transverse rollers at a bottom side thereof and a track mounted around the transverse rollers for movement by a user walking or running thereon. A wind resistance retarding assembly is mounted on the frame structure in front of the track which includes a series of fan blades rotatably driven by the rollers through a pair of spaced belt and pulley assemblies. The wind resistance produced by the turning fan blades is directed at the user and serves to retard the movement of the track when the user desires to slow the pace or disembark.
