Abstract
A device for athletic exercise by pulling at a resisting force. The device consists of a small cylindrical enclosure containing a number of constant force, circular wound spring assemblies, having a pulley molded to the enclosure, and having a force selector assembly connected to the enclosure which also serves to hold the device in any fixed location. A cord is wound around the pulley during assembly and its free end is attached to a pull-handle. A person uses the force selector by manually moving a spring-loaded adjustment knob through slots in the selector assembly to a slot which corresponds to the desired force level. This action causes a spring-engagement rod inside the selector assembly to engage the number of spring assemblies that will produce the selected resisting force when a person pulls at the pull handle. The device is small and light in weight. Provision is made for attachment of the device to any suitable restraining object or static equipment.
