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 rotatably attached to the base frame to undergo an adjustment to an inclined position at a certain angle. Moreover, a connecting rod between the upright frame and the base frame passes through a position-limiting tube to form an adjusting mechanism, whereby both handlebars are synchronically adjustable to allow the simulation of an oval exercise track in uphill or downhill position.
