Abstract

Abstract An apparatus for strengthening the bodies of individuals including a hexagon shaped grid or rack positioned above a surface of water such as created by a swimming pool. The hexagon shape of each component of the grid permits an individual to grasp alternately individual segments of the grid and progress in any direction relative to the water, either during exercise or specially designed games utilizing the improved features of the apparatus. The apparatus is particularly useful in connection with physical development of handicapped children. The grid itself is adjustably mounted with respect to the level of water permitting it to be raised or lowered to different heights above the water dependent on the age of the participant or his or her stage of development.
