Abstract
The present invention provides an apparatus that selectively facilitates exercises that approximate the motions involved in walking and cross-country skiing. A base extends from a front end to a rear end, and a treadmill is operatively mounted relative to the base. Each of a pair of foot skates is selectively placed in rolling engagement with an upwardly facing portion of the treadmill or upper treadmill surface. Each of the pair of foot skates includes a one-way clutch roller for rolling forward relative to the upper treadmill surface and preventing rolling rearward relative to the upper treadmill surface. Thus, rearward movement of either skate requires coincidental rearward movement of the upper treadmill surface.
