ABSTRACT:
An automatic force generating and control system including a lever pivotally attached to a monolith and a lower body exerciser pivotally attached to a bench, with both the bench and monolith attached to a platform. The rotation of the lower body exerciser is translated into linear movement by a series of sprockets and timing belts. The electrical output from load cells and potentiometers are processed by the electronic controls to determine the speed, direction and position and the amount and direction of force being exerted on the lever and lower body exerciser. Resistance to movement is provided by a lever hydraulics assembly and a lower body hydraulics assembly. The lever has arms and handles which articulate to the physique of the user and the exercise to be performed. The arms pivot in mirror relationship and the lower body exerciser may be lengthened or shortened. Electric solenoid clutches or hydraulics may engage the handles to the arms and the arms to the head of the lever. In an alternate embodiment, a mechanical linkage may transmit rotation between the arm and the lower body exerciser negating the need for one of the hydraulics assemblies.
