ABSTRACT:
An exercise assembly includes a substantially rectangular housing having planar front and rear surfaces with top, bottom, and two opposing side edges. Extending from the top edge is an extendable cord having a hook member at a distal end for securing the device to a door knob. The bottom edge has a pair of slots each having an axle mounted pulley received therein. A rope or cable is wrapped about each pulley which may be moved back and forth thereon. A digital electronic display means is disposed on the front surface and is in communication with a counting means for manipulating the output with each predetermined number of revolutions of a select pulley. The device also includes an alternative attachment means for securing the housing to non-conventional door knobs and similar support structures.
