Abstract: A method and apparatus for coupling a tubular handle (4, 6) of an exercise device to a flexible line (10), such as an elastic cord, is described. The elastic flexible line is directed through a circumferential opening (60) in the handle and attached to the inner lumen of the handle with a coupling assembly (24). The coupling assembly comprises a retainer (30) defining a hole (40) for receiving the end portion of the flexible line and fastener (32) for securing the end portion of the flexible line to the retainer to thereby fix the line to the handle. The coupling assembly provides a strong mechanical link between the flexible elastic line and the handle that minimizes wear on the elastic line.
