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°. 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° to 135° angle.
An exercising machine consisting essentially of: a main frame having a substantially top horizontal surface area; a hand rail attached to extend vertically from the frame; a tread roller which includes a pivotal cylindrical roller body having two ends, wherein two pairs of pedal means are rigidly attached between said ends to said roller body, approximately in the center of said main frame along a horizontal axis, each pair of pedal means having a traverse horizontally positioned pivotal axis and one elongated foot engaging means having a foot engaging surface at each end of said elongated foot engaging means, said pair of pedal means being mounted on said roller body at a 90° to 135° offset from the other of said pair of pedal means; a crank coupling means rigidly attached to each end of said roller body; and a resistance means comprising two dual action resistance cylinders, having two ends each wherein one end each of said resistance cylinders is pivotally secured to a forward side of the frame and a second end each of said resistance cylinders is pivotally connected to said crank coupling means so as to allow said roller body to be pivotally rotated in a clockwise or a counter clockwise rotation when in use.
