Abstract: A pair of foot pedals of an exercising device supported by rollers on a floor surface externally of a housing are interconnected by a linkage arrangement within the housing for simultaneous displacement in opposite direction in response to the prevailing foot pressure applied to either one of the pedals. The linkage arrangement is drivingly connected through one-way clutches to a common loading disc through which foot pressure applied to either of the pedals is resisted by a selectively adjusted amount to suit the user of the exercising device.
