An athletic exercising device comprising a handle mounted on swing arms pivotally mounted on a support tube that is vertically moveable on an upstanding standpipe and a spring loaded set pin for adjustably fixing the support tube in desired vertical positions on the standpipe. A piston-cylinder assembly is carried by the tube, and a closed hydraulic circuit is connected to the two ends of the cylinder. A piston rod is connected to the piston of the assembly and to the swing arms so that the arms and handle can be moved for exercising purposes against the action of the fluid acted on by the piston. The tube allows the assembly to be inverted on the standpipe and also to be rotated on the standpipe through 180 degrees for different exercises.
