Abstract: In an exercise apparatus having full body anaerobic, flexibility and stability capabilities, an inner core is positioned within an aperture of an inflatable apparatus. One or more flexible rods are provided for insertion within a portion of the inner core. The flexible rod may include one or more rings to which may be coupled a handle for tensioning movement of the flexible rod. The tensioning movement of the flexible rod while supported on the inflatable apparatus generates a resistive force for the user and provides anaerobic, flexibility and stability exercise.
