ABSTRACT:
An exercising apparatus of the rowing type having a seat freely slidable on a rail, feet stirrups, and poles representing oars that are provided with one-way resistance. With these features, the apparatus is usable as a conventional rowing-type machine. It is convertible to alternate use by the additional features as follows: the seat is provided with a backrest and the seat is reversible on the rail. The poles are pivoted front to back, the resistance being applied in one of these directions only, and are further freely pivotable side-to-side. The seat is locked in place in its reversed position so that the poles can be moved by the user between a position with the arms extended to the sides and the arms extended to the front. Such movement is resisted on the side-to-front motion only.
