An exercise device with compartment-housed weights sometimes used without all weights in place, adapted for use in a pool environment by a flap which is held in place over the compartment by "VELCRO*" hook and loop fasteners so as to contribute to providing a hermetic seal so that there is nominal seepage of water into empty compartments as might inadvertaently add to the weight used for exercise routines. * trade-mark
