1. An exercise device comprising:a pair of opposing axially-aligned elongated members each having a first end and a second end; first and second wheels being rotatably connected to each of the first ends of pair of the elongated members, respectively; and a connecting bar having each end operatively connected to the second end of each elongated member, the connecting bar being adapted for cooperation with the elongated members to selectively vary the distance between the elongated members, thereby controlling the width between said first and second wheels, wherein the pair of elongated members each include a centrally located axially aligned recess extending from the second end thereof, said recess being adapted for reversibly receiving and retaining an end portion of the connecting bar. 2. The exercise device of claim 1, wherein the elongated members each include a gripping surface for a user's hand.3. The exercise device of claim 1, further comprising a flange portion extending around a longitudinal axis of each of said pair of elongated members, proximate the respective first ends thereof adjacent to the associated wheel.4. The exercise device of claim 1, further comprising a locking mechanism adapted for reversibly locking the depth of the connecting bar end portions retained within the recesses of the second ends of said pair of elongated members, respectively.5. The exercise device of claim 4, wherein the locking mechanism includes:a plurality of spaced apart throughholes extending transversely through the connecting bar and arranged serially along the length of the connecting bar; a connecting port located through the circumference of each of said pair of elongated members proximate the respective second ends thereof, each said connecting port being alignable with the throughholes of an associated connecting bar end portion as its depth is varied within the recess of an associated elongated member; and a connecting pin adapted for snugly fitting into an aligned throughhole and connecting port to reversibly lock the associated connecting bar end portion within the recess at a depth. 6. The exercise device of claim 1, wherein:the connecting bar includes a longitudinal groove; and each of said pair of elongated members include a projection extending from an inside surface of their respective recess, said projection being adapted for sliding engagement within the groove of the connecting bar. 7. The exercise device of claim 1, wherein:the first end of each one of said pair of elongated members include a spindle extending away therefrom; and said first and second wheels each include a centrally-located throughhole for rotational mounting on the associated spindle. 8. The exercise device of claim 7, further comprising a pair of fasteners each adapted for securing the connection between said first and second wheels, and the spindle of the associated one of said pair of elongated members, respectively.9. The exercise device of claim 8, wherein:the spindle of each one of said pair of elongated members includes a threaded portion at the distal end thereof; and the pair of fasteners each include a nut adapted for threaded engagement with the threaded portion of the spindle against the associated one of said first and second wheels. 10. The exercise device of claim 7, wherein the spindle of each one of said pair of elongated members further includes a bearing surface upon which the associated one of said first and second wheels rotate.11. The exercise device of claim 1, further comprising:a pair of spindles each with a proximal end and a distal end; a bore extending internally from the first ends of each of said pair of elongated members, said bore being adapted for receiving and retaining the proximal end of a respective one of said pair of spindles; and a centrally-located throughhole in said first and second wheels for rotational mounting on said pair of spindles, respectively. 12. The exercise device of claim 11, wherein:each one of said pair of elongated members includes threads extending along the interior surface of its associated bore; and the proximal end of each one of said pair of spindles includes a threaded portion adapted for threaded engagement with the threaded bore of an associated one of the pair of elongated members. 13. The exercise device of claim 12, wherein each one of said pair of spindles includes a bearing surface portion between the threaded portion and the distal end thereof, said bearing surface being adapted for rotational engagement with and retainment of the associated one of said first and second wheels thereon.14. The exercise device of claim 13, wherein each one of said pair of spindles includes a handle at the distal end thereof.
