Abstract: An exercise device including an elongated exercise bar of non-circular cross-section having end members that include throughbores and a conical recess extending outwardly from the throughbore, and a slot communicating with the throughbore for permitting the lateral insertion into the throughbore of a tubular, elastic cable member. The elastic cable member includes one or more internally positioned plug members that provide local enlargement of the cable and are adapted to cooperte with the conical recess to securely position the cable with respect to the end member and to prevent the cable from passing through the end member when tension is applied to the cable.
