A wheeled exerciser includes a pair of main traction wheels, a pair of auxiliary wheels, a housing with a receiving compartment, a main wheel axle, a mounting piece which can be attached securely onto the housing, a set of coil springs which can be attached with one of the ends of each coil spring onto a mounting piece and with the other end of each coil spring attached to each of the main traction wheels in such a manner that the springs are winded when the wheels turn, and a pair of handles which can be attached to the outer surface of the housing. In use, the user holds the handles with both hands, presses the wheels of the exerciser against the floor, and pushes the exerciser forward from a starting point. In the course of pushing the exerciser forward, the main traction wheels turn and wind up the springs. When the exerciser reaches the desired position, the user moves the exerciser backward with the help of the restoring force on the springs. FIG. 1 shows the exerciser wheel in use.
