Abstract:
1. A track-adjusting method for an elliptical exercise apparatus, the track-adjusting method comprising the steps of: a) providing an elliptical exercise apparatus, which has a base frame and a supporting frame; a pair of lead swing arms pivotally connected to the supporting frame, each said lead swing arm being slidably mounted with a sliding treadle assembly; and a pair of subsidiary swing arms pivotally connected to the base frame, each said subsidiary swing arm being slidably mounted with a subsidiary sliding sleeve, wherein the adjacent sliding treadle assembly and the subsidiary sliding sleeve are pivotally connected to each other so that the swing arms interact to define a cyclic exercise track; b) providing at least one set of horizontally symmetrical pivot joints between the supporting frame and the swing arms of the elliptical exercise apparatus; and c) displacing the set of horizontally symmetrical pivot joints so as to alter the cyclic exercise track generated by the elliptical exercise apparatus.
