ABSTRACT:
An exercise device made from one or more lengths of metallic or a fiber reinforced plastic matrix material. A portion of the length of material adjacent opposite ends are attached to one another to form an annular spring in either a U-shaped, tear drop, elliptical, or circular shape. A hand grip and foot support are mounted to the annular spring. In one embodiment, the annular spring means is mounted in a metal housing of limited spring characteristics. The U-shaped, tear drop, and circularly configured annular spring has a stabilizing bar telescopically mounted to the annulus spring at diametrically opposite locations. The elliptical embodiment includes a pair of annular elliptical springs mounted one on top of the other at locations intersecting the minor axis. Other embodiments have a stabilizing bar offset from the annulus with one end of the bar fixedly clamped to the annulus and a portion of the bar adjacent the opposite end offset from the annulus and slidably clamped thereto.
One or more arcuate spring segments may be mounted to the annular spring for adjusting the weight range and bouncing characteristics. An elastomer band may be mounted to the annular spring of any of the embodiments so that it extends substantially parallel to the utility surface for increasing the weight range, and rebound of the device.
