A resistance exercise device comprising: at least one handle defining a plurality of holes; a cord having a pair of ends and a length extending between the pair of ends, the handle being secured to one of the ends of the cord, the cord being stretchable from a relaxed state to extend the length of the cord, the cord comprising a plurality of tubes extending substantially the entire length of the cord and having a pair of ends, the tubes being conjoined together along substantially the entire length of the cord by means of braiding, each tube received by a respective hole of the handle adjacent one of the ends of the tube; and structure engaging each tube to the handle adjacent the one end of the tube to prevent the tube from disengaging from the handle by preventing the one end of the tube from passing through the respective hole of the handle. The structure may comprise a plurality of plugs or other enlarged elements or any other suitable structure secured to a respective tube adjacent the one end of the respective tube to prevent the one end of the respective tube from disengaging from the handle. The handle may comprise one or more bores contiguous with each hole.

The invention claimed is: 1. A resistance exercise device comprising: at least one handle defining a plurality of holes; a cord having a pair of ends and a length extending between the pair of ends, the handle being secured to one of the ends of the cord, the cord being stretchable from a relaxed state to extend the length of the cord, the cord comprising a plurality of tubes extending substantially the entire length of the cord and having a pair of ends, the tubes being conjoined together along substantially the entire length of the cord by means of braiding, each tube received by a respective hole of the handle adjacent one of the ends of the tube; a plurality of enlarged elements, each enlarged element secured to a respective tube adjacent the one end of the respective tube to prevent the respective tube from disengaging from the handle by preventing the one end of the respective tube from passing through the respective hole by virtue of the respective enlarged element being larger than the respective hole; and wherein the handle defines a plurality of first bores and a plurality of second bores, each second bore contiguous with and interconnecting the respective first bore and the respective hole each enlarged element is sized to be receivable by the respective first bore and to be unable to pass through the respective second bore and the respective hole. 2. The resistance exercise device of claim 1 wherein each tube defines a channel at the one end of the tube and wherein each of the enlarged elements comprises a plug, each plug received by the channel of the respective tube expanding a portion of the respective tube, each plug being sized such that the expanded portion of the respective tube is unable to pass through the respective hole. 3. The resistance exercise device of claim 1 wherein each second bore is sized to receive the respective tube but unable to receive at least a portion of the respective enlarged element. 4. The resistance exercise device of claim 1 wherein each first bore is wider than the respective second bore. 5. The resistance exercise device of claim 1 wherein each enlarged element is generally tubular and each first bore and each second bore have a diameter, the diameter of each first bore and the diameter of each enlarged element are greater than the diameter of each second bore. 6. The resistance exercise device of claim 1 wherein each handle defines a plurality of first bores, each first bore contiguous with the respective hole, wherein each tube defines a channel at the one end of the cord, and wherein the structure comprises a plurality of plugs, each plug received by the channel of a respective tube expanding a portion of the respective tube, each tube received by a respective first bore and the respective hole adjacent the one end of the tube, each plug is sized such that the expanded portion of the respective tube is receivable by the respective first bore and is unable to pass through the respective hole. 7. The resistance exercise device of claim 6 wherein each first bore and each plug has a diameter, and each hole is generally circular, the diameter of each first bore and the diameter of each plug are greater than the diameter of each hole. 8. The resistance exercise device of claim 6 wherein the handle defines a plurality of second bores, each second bore contiguous with and interconnecting the respective first bore and the respective hole, each tube received by a respective second bore adjacent the one end of the tube, each second bore is sized to receive the respective tube but unable to receive at least a portion of a respective plug. 9. The resistance exercise device of claim 6 further comprising a plurality of sleeves, each sleeve disposed about the expanded portion of the respective tube. 10. The resistance exercise device of claim 1 further comprising an other handle secured to the other end of the cord. 11. The resistance exercise device of claim 1 wherein there are four of the tubes. 12. The resistance exercise device of claim 1 wherein the tubes are conjoined together by said means of braiding such that the tubes are snug along substantially the entire length of the cord when the cord is in the relaxed state. 13. The resistance exercise device of claim 1 wherein the tubes are conjoined together by said means of braiding such that when the cord is in the relaxed state each of the tubes is in contact with at least one of the other tubes substantially along the entire length of the cord when the cord is in the relaxed state. 14. The resistance exercise device of claim 1 wherein each of the tubes is hollow along substantially its entire length. 15. The resistance exercise tube of claim 1 wherein the handle is slidable relative to the tubes. 16. A resistance exercise device comprising: at least one handle defining a plurality of holes, a plurality of first bores having first bore diameters, and a plurality of second bores having second bore diameters smaller than the first bore diameters, each second bore contiguous with and interconnecting a respective first bore and a respective hole; a cord having a pair of ends and a length extending between the pair of ends, the cord being stretchable from a relaxed state to extend the length of the cord, the cord comprising a plurality of tubes extending substantially the entire length of the cord, the tubes being conjoined together along substantially the entire length of the cord by means of braiding, each tube received by the respective hole of the handle and the respective first and second bores, each tube defines a channel at the one end of the cord; and a plurality of plugs for securing the handle to one end of the cord, each plug received by the channel of a respective tube expanding a portion of the respective tube to a dimension greater than the second bore diameters but less than the first bore diameters, the expanded portion of the respective tube receivable by the respective first bore, each plug sized to prevent the respective tube from disengaging from the handle by preventing the expanded portion of the respective tube from passing through the respective second bore. 17. The resistance exercise device of claim 16 wherein the handle further comprises a rim defining the plurality of first and second bores, each rim separating the respective first bore from the respective second bore and engaging the expanded portion of the respective tube.
