An aquatic exercise device for use by an exerciser standing in a natural or man-made body of water. The device includes containers that fill with water when immersed and which have drainage openings formed in them so that they drain when lifted out of the body of water. The exercise device may include a single container that is lifted from the body of water by a pulley and cable mechanism, or it may include a single container connected to a rigid bar, mid-length of the bar, or it may be provided in the form of a barbell or a dumbbell having water containers at opposite ends of a rigid bar. In all embodiments, the flow rate of water draining from the container or containers may be adjusted to a flow rate selected by the exerciser. In the barbell, dumbbell, and central container embodiments, the containers are rotatably and eccentrically mounted with respect to an elongate or short or medium length bar, respectively, so that they invert when initially immersed and return to their repose position when lifted from the body of water, aligning the drain holes of the containers in their respective proper positions so that the containers drain at the same rate when lifted out of the water. The size, number and location of the fill and drainage openings may be varied. In all embodiments, the rigid bar is hollow and buoyant.
