  • Patent number: 7364530
    Abstract: A collapsible workout apparatus is disclosed. The apparatus includes a crossbar member with support legs pivotally attached at each end. The supports legs are operable to pivot outward to a trapezoid shape to form a self-standing structure with the crossbar member substantially parallel to the surface. A protrusion is pivotally attached at the base of each of the support legs. When extended outward, the protrusions also are substantially parallel to the surface. The crossbar member and protrusions, when extended, are operable to enable a user to perform push-ups or pull-ups efficiently. The support legs and protrusions can be pivoted to be substantially parallel to the crossbar member for easy storage and portability.
