An elongate bar having sliding handgrips concentrically mounted thereon adapted for use with a resistance-type exercise device. In a preferred embodiment, the bar has at least two, and more preferably four, axially oriented grooves in the outer surface thereof dimensioned to accommodate handgrip linking means therewithin. The handgrips, which are constrained to move only in an axial direction, are interconnected by linking means such as belts, in such a manner that the handgrips remain equidistant from the center of the bar throughout their axial range of motion. The interconnecting belts or cables are disposed to travel within the elongate grooves on the bar to provide the bar with a low profile. In the preferred embodiment, the linking means are belts that are supported by pulleys housed within recesses in the bar and rotatably attached thereto. The bar further includes resistive force attachment means operable for attaching weights, springs, cable(s), elastic bands or the like thereto to provide a resistive force. In a further embodiment, the bar includes floor supporting means and can be used for performing pushups. In yet a further embodiment, the bar includes wall attachment means and can be employed for performing pull-ups.

What is claimed is: 1. A resistance exercise device comprising: (a) an elongate, free-standing, nonbifurcated, substantially cylindrical bar having first and second ends and a center plane therebetween, said center plane intersecting said bar at a center of gravity thereof; (b) first and second handgrips slidably mounted on said bar and disposed equidistant from said center plane wherein said handgrips have a longitudinal axis and can be slidingly moved on said bar in a direction parallel to said longitudinal axis of said handgrips; and (c) coupling means housed in recesses in said bar, said coupling means connecting said first handgrip to said second handgrip, said coupling means being operable for maintaining said first and second handgrips equidistant from said center plane when said first and second handgrips are moved in a direction parallel to said longitudinal axis of said handgrips. 2. The resistance exercise device of claim 1 further comprising resistive force attachment means affixed to said first and second ends of said free-standing bar, said resistive force attachment means being operable for removably attaching weights to said free-standing bar. 3. The resistance exercise device of claim 2 wherein said resistive force attachment means are disposed equidistant from said center plane of said free-standing bar. 4. The resistance exercise device of claim 1 further comprising tubular sleeves rotatably and concentrically mounted on said first and second handgrips. 5. The resistance exercise device of claim 1 wherein said free-standing bar has a weight and wherein when an exercisor grasps said first and second handgrips and exerts a force to elevate said free-standing bar, said weight of said free-standing bar provides a resistive force in opposition to said force exerted to elevate said free-standing bar. 6. A resistance exercise device comprising: (a) an elongate, nonbifurcated, substantially cylindrical free-standing bar having a weight, a length, a plurality of grooves in an outer surface thereof and a longitudinal axis coextensive with said length defining an axial direction, said cylindrical free-standing bar having first and second ends and a center plane therebetween wherein said center plane intersects said cylindrical free-standing bar at a center of gravity thereof; (b) first and second handgrips disposed on said cylindrical free-standing bar equidistant from said center plane, said first and second handgrips adapted to provide means enabling an exercisor to grasp said cylindrical free-standing bar; and (c) coupling means comprising belts interconnecting said first and second handgrips, said belts disposed within said grooves in said free-standing bar, said coupling means being operable for enabling said first and second handgrips to be moved relative to each other in said axial direction while maintaining said first and second handgrips equidistant from said center plane. 7. The resistance exercise device of claim 6 wherein when an exercisor grasps said first and second handgrips and exerts a force to elevate said cylindrical free-standing bar, said weight provides a resistive force in opposition to said force exerted to elevate said cylindrical free-standing bar. 8. The resistance exercise device of claim 6 wherein said cylindrical free-standing bar further comprises weight attachment means adjacent to said first and second ends and equidistant from said center plane, said weight attachment means being operable for removably attaching weights to said cylindrical free-standing bar.
