Abstract: A rotary exercise system in one embodiment includes a chassis configured for mounting to stationary support members, a rotational support shaft rotatably coupled to chassis, and handle bar assembly coupled to the support shaft and manually rotatable therewith by a user. A variable resistance mechanism applies a user-adjustable rotational resistance force on the support shaft, which changes the force required to be applied by the user to rotate the handle bar assembly during an exercise routine. In some embodiments, the resistance mechanism may be a frictional resistance mechanism, such as a drum or disc brake assembly. A user-operated control actuator allows the user to readily change resistance settings to increase or decrease the rotational resistance imparted to the support shaft by the resistance mechanism. In some implementations, the chassis may be detachably mounted on vertical supports of a power rack and adjustable in height for performing different exercise routines.

Abstract: A weight lifting bench and hydraulic cylinder assembly for operating the bench and other equipment are disclosed. The assembly comprises a hydraulic cylinder containing a hydraulic fluid and extendable/retractable piston rod, an accumulator containing a pressurized compressible fluid, and a flow control valve assembly interposed in a flow path therebetween. The flow control valve includes an axially reciprocating piston defining a flow control orifice and an axially movable plunger received in the orifice. Movement of the plunger operates to engage and open a ball check valve which in turn opens the flow path allowing hydraulic fluid to flow from the hydraulic cylinder to the accumulator. Reciprocating movement of the piston opens and closes the flow path to control the retraction rate of the rod. The flow control valve is operable to automatically extend the rod. Various embodiments of the bench incorporating the hydraulic cylinder assembly and operating methods are disclosed.
