Abstract: An aquatic exercise device is disclosed. The aquatic exercise device is adapted to be submerged in water, and moved through the water and/or rotated in the water to provide omni-directional and omni-rotational drag resistance. In one implementation, an aquatic exercise device includes a bar adapted to be grasped by one or two hands of a user, and a resistance mechanism attached to opposite ends of the bar. Each resistance mechanism includes a cuff and two or more fins extending outward from the cuff.
