A method for generating a rebounding motion between a person and a stationary surface comprising the steps of providing a rebounding device that includes a front member, a rear member, and a spring mechanism positioned between the front member and the rear member for allowing the front member and rear member to move toward and away from one another. The method further includes the steps of positioning the rear member against the stationary surface and the front member adjacent to an upper body of the person and the stationary surface, and applying pressure to the rebounding device through the upper body such that the upper body moves toward from the stationary surface while a lower body of the person remains in place.
