Exercise bar apparatus

An exercise bar apparatus, comprising,

• an elongate, coaxially aligned polygonal body defined by adjacent flats coextensive with the polygonal body, the polygonal body including a central support rod coextensively directed through the polygonal body, wherein the support rod includes an internally threaded socket formed at each terminal end of the central support rod, each internally threaded socket includes an externally threaded rod mounted thereon, and each externally threaded rod includes a polymeric cap mounted thereon, and
• a plurality of equally spaced caged roller bearings positioned within the polygonal body mounted between the polygonal body and the central support rod rotatably mounting the polygonal body to the central support rod, and
• a support cup mounted relative to each cap for receiving the cap therewithin, and each support cup is orthogonally and integrally mounted to a support flange, wherein each support flange is adapted for mounting to a vertical interior surface of a door frame, and
• wherein the polygonal body further includes a central polygonal body portion defined by a first diameter, the central polygonal body portion including a respective first and second polygonal body extremity portion mounted at each terminal end of the central polygonal body, wherein the first and second polygonal body extremity portions are coaxially aligned with the central polygonal body, and the central polygonal body is defined by a first diameter, the first and second polygonal body extremity portions are defined by a second diameter, wherein the second diameter is greater than the first diameter to accommodate an individual of an enlarged hand grasp for securement to the first and second polygonal body extremity portions, and wherein an individual of a reduced hand grasp is accommodated upon the central polygonal body portion.
