The water exercise device also includes a means for supporting the foot rest assembly and includes an attachment assembly and a flotation device. The attachment assembly is for mounting to a structure such as the wall of a pool or a ladder and is configured to securely hold the foot rest assembly. The flotation device is secured to the foot rest assembly to float on the surface of the water and maintains the water exercise device below the water.
