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.

Abstract: An exercise apparatus includes first, second, third and fourth elongated frame members respectively defining a first, second, third, and fourth frame portion each comprising interior and exterior perimeters. The first frame member can include first, second, third, and fourth segments. The first frame portion can encompass first and second open interior regions. The third frame member can adjoin the first frame member at spaced first and second points on the first frame member and span from the first point to the second point. The fourth frame member can adjoin the first frame member at spaced third and fourth points on the first frame member and span from the third point to the fourth point.
