ABSTRACT:
An exercise apparatus includes a bench support, and an input bar pivotally mounted on the bench and movable through a work cycle in response to forces exerted by a user. A hydraulic actuator is connected to the input bar for developing a resistive force against the movement of the bar. An adjusting mechanism enables a user to vary the resistive force. A pressure transducer senses the pressure in the hydraulic actuator which is representative of the input force exerted by a user, and a potentiometer located at the pivotal connection of the input bar on the bench measures the angle of rotation of the bar which is representative of the displacement of the bar. The force and displacement input signals are employed by a microprocessor to generate output signals to a display showing the cycle count, the input force or the work accomplished by a user during each cycle.
