ABSTRACT:
A resistance assembly for a hydraulic resistance exercise apparatus includes a single-action hydraulic cylinder having a longitudinal axis and extending from a first end to a second end. The single-action cylinder provides resistance to compression of the cylinder, one end toward the other, but provides little or no resistance to extension of the cylinder, one end away from the other. A first compression linkage compresses the hydraulic cylinder in response to movement of a first exercise resistance lever in a first direction. A second compression linkage compresses the hydraulic cylinder in response to movement of a second exercise resistance lever in a second direction directly opposed to the first direction. An engagement exercise lever includes an engagement pin for selectively engaging the engagement exercise lever to move in fixed relation to one or the other the first or second exercise levers in both the first and second direction.
