This invention pertains to a foldable jogging simulator in which each of the ends of two corresponding C-shape joint-bar pedals set has an action crank which powers a gear plate. Each of these gear plates has a toothed chain which is linked to a small gear. The two small gears on both sides are connected to the same pivoted shaft, providing a coordinated action with the two joint-bar pedals set. Furthermore, since a retarding wheel is installed in the middle of the pivoted shaft, a retarding force of motion is created; and as the other end of the joint-bar pedals set is installed with a coaxial sliding wheel, which adjusts is position (up and down) due to the rotation of a threaded column, the accidental disconnection of two pedals set is prevented. Finally, the base of the slanted support bar at the front portion is pivotally connected to a horizontal bar in the front of the machine, and this allows the machine to be folded, reducing its size and facilitate storage or transportation.
