Abstract: An exercise apparatus is disclosed, comprising a first frame, a second frame aligned about parallel to the first frame, and at least three crossbars extending about orthogonally between inward faces of the frames. Each of the first frame and the second frame includes at least three vertices, at least three sides extending between the at least three vertices, at least three attachment struts disposed inward from the at least three vertices, and at least three load posts extending from an outward face of the frames. The at least three sides of each frame are formed of at least three frame struts. The at least three crossbars attach to one of the at least three attachment struts of the first frame and one of the at least three attachment struts of the second frame. The load posts are arranged and disposed to receive and releasably retain a plurality of weights.
