Exercise apparatus having cylindrical frame member

Abstract

An exercise apparatus of the present technology may include a cylindrical shaped first frame member that defines a substantially cylindrical first frame portion. The cylindrical shaped first frame member/portion may have an exterior surface, an interior surface, a first radius between the interior surface and the center of the cylindrical shape, a second radius between the exterior surface and the center of the cylindrical shape, and a thickness as the difference between the first radius and the second radius. The exercise apparatus of the present technology that includes the cylindrical first frame member may include different sizes of frame members, for example cylindrical portions having a different length along the center axis of the cylinder, in order to achieve different weights for the exercise apparatus.
