ABSTRACT:
A leg exercising device including a frame, a pair of pedal arms pivotally secured to the frame, a double acting hydraulic cylinder having a chamber and a piston movably disposed therein, and a pair of valves connected to the hydraulic cylinder for controlling flow of fluid to and from the chamber on opposite sides of the piston. Foot engaging straps on the pedals exert a force in opposite directions toward and away from each pedal as a result of movement of the foot of a user in opposite directions. The valves are mounted adjacent the pedal within the reach of the user whose foot is in engagement with the foot engaging straps to permit independent adjustment of the magnitude of force resisting movement of the pedal arms in opposite directions.
