Abstract: A non motorized bidirectional jogging apparatus having a rectangular base member with a roller assembly formed on the base member. A level adjustment device is coupled to the base member in order to adjust the angular incline of the base member relative to the support surface. A collapsible frame extends upwardly from the base member. The collapsible frame consists of four upright posts hinged at their lower ends to the respective front and rear corners of the base member. Grasping rods axially extend from the front upright posts. A handlebar interconnects the top of the two rear upright posts. Side rails each respectively pivotally coupled to a front and rear upright post are each formed in two sections which are releasably coupled together so that on uncoupling, the frame can be folded flat. The hinges include stops to limit hinging of the posts between their upright and folded positions.

Abstract: An exercising apparatus having a base member with a roller assembly positioned on the surface of the base member. The roller assembly is formed of an array of discrete rollers having a series of parallel axles with closely spaced rollers mounted on the axles for individual rotation and supported by support bars. A frame upwardly extends from the base member and defines an enclosed exercising area. The frame includes both front and rear handle bars. The base member can be adjustably positioned at a variable incline with respect to the support surface on which it rests. The exercising apparatus can be used for walking, jogging, as well as exercising of the arms and shoulders and permits both uphill and downhill exercising.
