ABSTRACT:
A track-adjusting method and a track-adjusting mechanism are applicable to an elliptical exercise apparatus using a linkage system to generate a cyclic exercise track. The track-adjusting method and the track-adjusting mechanism provide the elliptical exercise apparatus with additional exercise tracks by displacing at least one set of horizontally symmetrical pivotal joints in the linkage system, so as to allow diverse training programs and improved exercise effects.
