ABSTRACT:
Exercise machine having a base comprising a horizontally extending platform and an upstanding post. A swing arm comprising has a pair of arms and a crossbar is pivotally mounted on the post for movement about a horizontally extending axis, with the crossbar extending in a direction generally parallel to the axis. A first pair of pulleys are mounted on the base in alignment with the horizontally extending axis, and a second pair of pulleys are mounted on the crossbar. A pair of cables are trained about the pulleys, grips are connected to the cables near the second pulleys, and resistance elements are connected to the cables for yieldably resisting movement of the cables when a pull is exerted thereon. A pair of telescoping arms extend between the base and the crossbar for holding the crossbar and the grips at different heights above the platform.
