Abstract
A weight lifting body exercising apparatus comprised of a base member and one or more beams forming an upstanding frame. A vertically shiftable movement against one or more weights which may be selectively introduced. The user of the apparatus effectively lifts the weight or weights by pulling on a cable connected to the weight or weights. In some cases, the user effectively lifts the weights by pulling on the cable and moving the carriage. A first pulley is mounted on the frame above the carriage and at a height generally above the height of the user. A second pulley is mounted at the base and is located forwardly of the first pulley. A third pulley is mounted on the frame at a height generally above the height of the user and located immediately vertically above the user. In one preferred embodiment of the invention, a fourth pulley is located on the carriage. The cable may be secured to the carriage or trained around the fourth pulley on the carriage. A handle mechanism, and preferably an adjustable handle mechanism, is associated with the carriage and engagable by a user to apply a force and thereby attempt to shift the carriage against the one or more weights.
