ABSTRACT The present invention provides an exercise device comprising a frame; a rotatable axle on the frame; a body-engaging means for rotating the axle; and a counterweight assembly connected to the axle for producing a static counterforce to rotation of the axle. The counterweight assembly includes a tank for holding a fluid at a predetermined level, means for varying the predetermined fluid level in the tank, and at least one wheel drivingly connected to the axle and rotable about a non vertical axis, the wheel having a plurality of troughs spaced uniformly around the axis, the troughs being positioned to pass through the tank as the wheel is rotatably driven by the body engaging means, receive at least a portion of fluid in the tank, carry the received fluid above the predetermined fluid level and discharge the received fluid at a position above the predetermined fluid level. In its preferred embodiment, the present invention utilizes a plurality of counterforce assembly wheels, each rotating through a liquid and having progressively varying trough liquid volumes about the peripheries thereof, and means for adjusting the desired relative angular orientation of the wheels, for varying the maximum and minimum static counterforce as the wheels are rotated through one revolution.
