An adjustable weight lifting bench includes a frame, a seat pad, and a back pad. The back pad is pivotably coupled to the frame about a first pivot axis and angularly adjustable between a plurality of user-selectable incline and decline positions. A hydraulic mechanism supports the back pad in the incline and decline positions. A movable operating lever operably coupled to the hydraulic mechanism operates to change the mechanism between an activated condition in which the back pad is movable and a deactivated condition in which the back pad locks into a selected one of the positions. When the mechanism is in activated condition, applying pressure against the back pad the lowers the back pad and removing the pressure raises the back pad. In one embodiment, the mechanism automatically raises the back pad when the pressure is removed and the mechanism is in the deactivated condition.

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.

A hydraulic cylinder assembly for operating a weight lifting bench and other equipment. The hydraulic cylinder assembly comprises a hydraulic cylinder containing a hydraulic fluid, 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. The working end may be stepped and positionable between first and second axial positions relative to the orifice to define first and second flow areas via movement of the plunger. Reciprocating movement of the piston opens and closes the flow path.
