ABSTRACT:
An exercising machine for bodybuilders which facilitates the safe and proper performance of various lower body exercises such as squats and lunges. The machine safely facilitates free, natural movements in two planes to promote muscle growth and bone and tendon strength. The machine is ideally suited to use as a rehabilitation device. A rigid steel frame of generally rectangular configuration rests upon a resilient, skid-resistant mat. The frame comprises rigid, spaced apart side rails and parallel cross members. A carriage assembly is slidably disposed upon the rails for movement along the frame. The carriage assembly includes a pair of rigid, parallel arches which extend vertically from roller assemblies associated with the frame rails. The roller assemblies comprise twin-bearing pillow blocks which permit the carriage to roll securely along the rails. A weight bar system extending between carriage sides may be loaded as desired by the bodybuilder. The weight bar system includes a horizontal weight bar contacted by the exerciser and rotatable, offset weight supports. A padded yoke associated with the weight bar harnesses the exerciser to the machine. Vertical guide rods associated with each side of the carriage assembly establish a vertical path for defining upward and downward movement of the weight bar. Weight bar sleeves coaxially mated to the guide rods enable vertical movement of the weight bar during operation. A weight bar restraint system safely retains the weight bar in a desired elevated position until released by manipulation of an associated pair of handgrips by the exerciser. A selectively positionable auxiliary drop bar prevents injury to the bodybuilder as a result of inadvertent release of the weight bar assembly during operation.
