Abstract: An attachment which can be mounted on popular weight lifting exercise equipment, to facilitate workouts using hand-held weights commonly referred to as dumbbells. The attachment comprises a rack assembly on which an athlete can support up to two dumbbells simultaneously. Readily adaptable for use with any weight lifting bench, the attachment includes a pair of mounting legs rigidly attached to distal ends of the rack assembly and an extension bar slideably connected to opposing parts of this assembly for adjusting the span between these mounting legs. By utilizing the span adjusting means, one can align the mounting legs with the weight support columns of any particular weight lifting bench even though the spacing between these columns may differ substantially from that of other benches.
