ABSTRACT:
An exercising machine which consists essentially of a main frame, a handrail, a tread roller and two fluid pressure cylinders, wherein the main frame is designed to support and install all members concerned, the handrail may be fixed or adjustable in favor of being adjusted up and down so as to fit the height of different exercisers. The tread roller is a cylindrical roller body whereon two-pair of steps are positioned in an upward and downward position in the center of a roller body, separated from each other by an angle of 90.degree.. The roller body is pivotally installed, roughly, in the center of the main frame capable of rotation clockwise and counterclockwise. One crank coupling each is fixed on the two ends of roller body; the two fluid pressure cylinders are equipped with a bilateral resistance action and respectively and pivotally installed in a position nearby the front, on the side of the main frame. The end of thrust rod on these cylinders is respectively connected to and pivotally installed on the crank coupling, on the two sides of tread roller. The positions of pivotal installation have to be separated from each other with a 90.degree. to 135.degree. angle.
