A variable drag and buoyancy kickboard for a swimmer comprising a first portion, a second portion, and a plurality of pairs of hand grasping locations. The second portion extends from a lateral edge of the first portion. The first portion defines a first planar surface and the second portion defines a second planar surface. The first and second planar surfaces form an obtuse angle. The first and second portions having a periphery upon which the hand grasping locations are disposed. Each pair of hand grasping locations are laterally opposite each other on the periphery. Grasping different pairs of hand grasping locations varies the flow characteristics of the kickboard by varying its position in the water. Thus, the drag of the kickboard may be varied.
