A continuous swimming apparatus is provided which minimizes power requirements by providing higher water velocity through that portion of the swimming area in which the swimmer is located, and lower velocity in unused portions of the tank. This water velocity gradient is produced by an arrangement of turning vanes in the recirculation paths of the apparatus. The water velocity may be varied by adjusting hydraulic fluid flow to hydraulic motors which drive propellers for circulating the water through the apparatus.
