A compact exercising device in which the contractable and expandable parts are arranged in axial alignment and include a hydraulic piston and cylinder resistance coupled with an axially entensible cable and pulley system. The cylinder has its opposite ends interconnected by a conduit which incorporates a metering valve which provides a preset resistance to flow of the fluid in one direction and allows the fluid to flow quickly with little resistance in the opposite direction.

DETAILED DESCRIPTION We claim: 1.
An exercising device comprising a pair of spaced fixedly interconnected end members and an intervening hydraulic resistance operative between said end members including a piston rod connected to said end members, and a cylinder slidable on said rod between the ends thereof and means for transferring fluid from one end of the cylinder to the other pursuant to movement of said cylinder on the rod, means for anchoring said device, and operating means for manipulating said cylinder by the user pursuant to performing exercising movements and said operating means comprises a pulley and cord mechanism reactively connected between said cylinder and one of said end members and having handhold means for grasping by the user and pulling on the same.
2.
The invention according to claim 1 wherein said mechanism extends axially of the cylinder and said handhold means extending transversely of the axis of the cylinder.
3.
An exercising device comprising a pair of end members and an intervening hydraulic resistance operative between said end members including a piston rod connected to said end members, and a cylinder slidable on said rod between the ends thereof and means for transferring fluid from one end of the cylinder to the other pursuant to movement of said cylinder on said rod, means for anchoring said device, and operating means for manipulating said cylinder by the user pursuant to performing exercising movements, and said operating means comprises a pulley and cord mechanism operatively connected to said cylinder, and said mechanism comprises a set of pulleys mounted on one of said end members and means mounting a complementary set of pulleys connected to one end of said cylinder, and said cord having a plurality of lengths of cord twined about said pulleys and having a portion intermediate its ends providing a handhold.
4.
The invention according to claim 3 and resilient means connected between said one end of said cylinder and the end member remote from said one end for retracting the cylinder toward the same
