ABSTRACT:
A variable resistance exercising device is described for doing isometric, isotonic and isokinetic exercises. The device includes a unitary, tortuous rod, which is shaped to include at least one mandrel for receiving several turns of a rope, a first loop for receiving the rope near one end of the mandrel, and an overlapping curl for receiving both the rope and an adjustably mountable anchor strap at an opposite end of the mandrel. The shape of the rod is such that there are no tight radius curves. Also, the rod creates a cord-receiving throat that allows the rope to be readily inserted and removed; yet the throat inhibits the rope from falling out from within the loop when tension in the rope is released.
