An exercise method and device for alleviating lower back stiffness through continuous passive motion (CPM) mimicking that experienced by a person mounted on a horse at the walk. The device and method of the present invention are envisioned as being used in gymnasiums as well as health practitioners' offices, by trainers and physical therapists treating subjects with lumbar stiffness and pain, on the one hand, and by those subjects themselves who may seek relief and greater range of motion without professional assistance. With the subject seated upright on a backless seat, with his or her spine self-supported and in proper vertical alignment, the seat is accelerated, alternatingly, forward and backward, thus imposing a horizontal to-and-fro force to the lower part of the subject's body at such frequency and excursion-amplitude that that part of the body is caused to move with respect to the upper part of the body. To permit this greater excursion of the lower body with respect to the upper, the lumbar spine bends; the resultant effect of this lumbar-spine bending is relief of stiffness--and, ultimately, discomfort--in the lumbar spine area.
