ABSTRACT:
An apparatus utilizing squat maneuvers is provided for exercising and/or rehabilitating muscles and joints in the lower back, hip and legs. A single carriage assembly comprising four elongated members pivotably connected in the form of a rectanglar provide a parallelogram-type arrangement which provides a pantographic-type motion to a vertically oriented back support that is supported in cantilever fashion by a vertically disposed member of the carriage assembly. The back support is maintained in its vertical orientation during squat maneuvers while being moved along an arcuate path as provided by the pantographic motion of the carriage assembly. The elongated members of the single carriage assembly are formed of structures exhibiting high resistance to twisting moments and the pivotal connections between these members are of near pressed-fit tolerances so as to inhibit any looseness at the pivotal connections which could cause binding at the pivotal connections during squat maneuvers. Adjustable shoulder blocks and a transverse rod associated with the back support are adapted to be contacted by the user for effecting squat maneuvers including bar bell-type squats.
