A kickboard having a rigid base of generally thin, rectangular, shape. At least one shallow cutout or depression is formed in the top surface of the base, the depression extending rearwardly from near the front edge of the base and being at least wide enough and long enough to receive a swimmer's arm when the swimmer grips the front edge of the base with his hand. A layer of cushioning material in the depression cushions the arm of the swimmer while gripping the board by the front edge. The front edge of the board is rounded and at least partly cushioned as well. A groove is provided in the bottom surface of the base positioned to receive the finger-tips of the swimmer while gripping the front edge. A second groove can be provided in the top surface of the base, just behind the finger-tip groove, for receiving a portion of the palm of the swimmer's hand while gripping the front edge.
