Abstract: An aftermarket adaptor apparatus for a float-board is disclosed. My invention permits a user to adapt a conventional buoyant water float-board (typically a “stand-up paddleboard”, surf board, or other floatable device), to effectively convert it into a foot-propelled exercise board. The adapted float-board allows a user to travel across, over, and through water by the action and means of the user's feet treading and ambulating upon a treadmill integral to said adaptor apparatus (after its attachment onto said float-board). In practice, the treadmill is affixed onto and over the upper surface of the float-board at the time of the adapter being attached. Accordingly, the affixed adaptor upgrades a simple float-board for treadmill propulsion through the water. The adapted float-board permits a user to “self-propel” over, across, and through a body of water.
