EXERCISING DEVICE WITH DOUBLE ACTING HYDRAULIC CYLINDER ABSTRACT OF THE DISCLOSURE An exercising device comprising a frame, actuating means, and a double acting hydraulic cylinder used therewith. The hydraulic cylinder includes a container having first and second chambers and passageways for placing the chambers in fluid communication with one another. A piston is slideably mounted within the first chamber and valve means are mounted with the container for preventing fluid communication into the first chamber when the piston is moved in a first direction and for preventing fluid communication around the piston when the piston is moved in a second direction. A piston rod extends into the container for moving the piston in response to movement of the actuating means. A control means governs the fluid flow through a selected passageway from the first to the second chamber to regulate the amount of force necessary to move the actuating means during exercise of a portion of the body.
