ABSTRACT:
An oval-tracked exercise apparatus with an adjustable exercise track having a frame unit consisting of an upright frame and a base frame. A hanging handlebar is provided at both sides of the upright frame. One end of two planks is pivotally attached to the bottom end of the handlebars while the other end thereof moves up and down in alternating succession above the base frame. In this way, an oval walking track can be simulated in treading the treadles. The upright frame is movable in reciprocating state by use of a rack. A drive mechanism is employed to manually or automatically control the movement of one of both frames to a preset position so that both handlebars can be synchronically adjusted to simulate an oval-tracked walking exercise in uphill or downhill position.
