The present invention discloses a fitness machine with elliptical and stepping functions for integrating a stepping exercise and an elliptic exercise for exercising users' legs as well as a swing exercise for exercising users' arms. The fitness machine comprises a frame, two sliding rods, two pedals, and two support rods. If the two support rods are fixed to the frame, the two pedals will be limited such that the two pedals produce an up-and-down stepping exercise. If the two support rods are fixed to the sliding rods, then the limiting effect of the pedals provided by the support rods will be diminished, so that the two pedals produce a back-and-forth elliptic exercise. Regardless of the stepping exercise or the elliptic exercise, the two swinging arms are linked by the two sliding rods and swung back and forth, so as to provide both exercisers for legs and arms.
