Abstract: An endless cord exercise machine in which a user applies a continuous pulling motion to a cord that is attached to a resistance mechanism is disclosed. The machine may be arranged to simulate the acts of rope climbing or of scaling a wall with the assistance of a rope, or may be arranged to provide other types of upper and lower body muscle development. The resistance mechanism is ideally comprised of a plurality of rotary viscous dampers of differing viscosities housed in a rotating drum. A spring-loaded adjustment key mechanism extending through the hub of the drum and dampers allows the user to selectively engage any combination of dampers to provide exercise resistance.

Abstract: A cord retaining apparatus includes a receptacle for receiving a head of a cord. A brack is mounted near the receptacle including an upper stop. An arm is pivotally attached to the bracket. A first length of the arm extends distal from the receptacle and a second length of the arm is substantially perpendicular to the first length. The arm is movable into and out of a position in which the second length is behind the head of the cord preventing removal of the cord. The upper stop prevents the arm from moving into a position where the arm does not naturally fall into the position behind the head of the cord.
