A kickboard for a swimmer which has a rigid, smoothly contoured, buoyant body symmetrical about a longitudinally extending notional plane perpendicular to its top surface and passing through a center thereof. When referenced to the kickboard being supported by a flat horizontal support surface, the top surface is inclined rearwardly, along the intersection with the notional plane, from a front peripheral edge and upwardly from the support surface reaching a maximum and then curving downwardly toward the sides and in a rearwardly direction. A central curvilinear opening extends from proximal the maximum with opening peripheral side edges extending rearwardly, spaced away from respective outer peripheral side edges of the body so as to provide contoured elongated arm receptacles. A bottom surface of the body follows a similar profile as the overlying top surface.
