Abstract

There is provided exercising apparatus having an elongate frame (10) housing a longitudinal hydraulic main cylinder (13), one end of which is fixedly mounted relative to a mounting end (11) of the frame, sealing means (20) being provided at the other end of the main cylinder (13) through which a plunger rod (15) is sealably slidable, handle means (21) being associated with that end of the plunger rod (15) which is external.
There is pro-vided a main piston (18) at the inner end of the plunger rod (15) to define two opposite sides of the main cylinder (13), the latter having adjustable aperture means (l6, 17) inter-connecting said two sides for adjustably varying the permitted flow of hydraulic liquid from one to the other upon movement of said plunger rod (15) and said main piston (18).
There is also provided a displacement cylinder (22) mounted on the frame (10) and having one of its ends in liquid communication with the main cylinder (13), while a closure piston (23) is mounted in sealably slidable manner in the other end of the displacement cylinder (22) and movable in response to movement of the main piston (18) and the plunger rod (15) to maintain a liquid-filled condition of the main cylinder regardless of the positions occupied by the main piston and the plunger rod.
