A foot and/or leg-exercising device ( 10 ) has a first sealed chamber ( 14 ) and a second sealed chamber ( 16 ) that are interconnected via one or more passageways ( 34 ). The chambers ( 14, 16 ) are of variable volume and fluid within one chamber may be pumped to the other chamber using the feet and/or legs. In one embodiment each foot is provided with a first chamber and a second chamber and fluid is pumped by a heel and toe rocking action of each foot. The chambers for both feet may be interconnected to allow pumping by an up and down action of the legs.
