A swimming hoop with a buoyancy member and flexible frame. By increasing or decreasing the buoyant force provided to the flexible frame by the buoyancy member, the user is able to position the swimming hoop at a desired vertical distance within a body of water. To increase or decrease the buoyant force, a pump is used to increase or decrease the level of air within an air chamber. The buoyancy member is adjustably secured to the flexible frame. The flexible frame may be generally circular, square, or any other shape, and is flexible such that other shapes can be further obtained by twisting or manipulating the flexible frame. |
