Abstract
A walking/jogging exercise machine includes a frame supported upon a generally horizontally extending floor, and a main driveshaft mounted for rotation on the frame. A pair of cams is mounted for rotation on the driveshaft, and a pair of first track assemblies is fixed to the frame. A pair of second track assemblies is rotatably attached to the frame and includes brackets having first rollers which ride upon the peripheries of the cams. A pair of non-aligned, foot assemblies are mounted for sliding movement on the first and second track assemblies. A linkage arrangement is provided between the drive shaft and the foot assemblies for transferring the movement of the foot assemblies to the cams so as to produce a change in the angle of a user's ankle which will result in a natural walking/jogging motion.
