Abstract Rowing apparatus having a substantially rectangular frame for alternative support on a horizontal surface and a vertical surface. The frame has parallel side members and a seat carriage with means for sliding movement on the side members. A first tension spring means is provided with means removably connecting the tension spring means between the seat carriage and the front of the frame. Two handles are at opposite sides of the frame and a separate line is attached to each handle. A pair of first pulleys are connected to the front of the frame and a pair of rear pulleys connected by a second tension spring means to the rear of the frame. The lines pass respectively from each said handle, round the first pulley, round the rear pulley and then forwardly whereby each rear pulley is acted on by at least two runs of line so that after removal of the seat carriage the apparatus may be mounted vertically for arm exercising. A crossbar is mounted on the front of the frame serving as a footrest in the horizontal position of the frame and as a handgrip in the vertical position of the frame.
Rowing apparatus comprising a substantially rectangular frame for alternative support on a horizontal surface or vertical surface, said frame comprising parallel side members having a back support means between said side members for use on said vertical surface, a removable seat carriage, means mounted on said seat carriage facilitating said carriage''s sliding movement on said side members, first tension spring means, means for removably connecting said tension spring means between said seat carriage and the front of said frame, two handles at opposite sides of said frame, a separate line attached to each of said handles, said lines running along the sides of said frame exterior of said side members, a pair of front pulleys connected to the front of said frame exterior of said side members, a pair of rear pulleys exterior of said side members, a second tension spring means connecting said rear pulleys to the rear of said frame exterior of said side members, said lines passing respectively from each of said handles around said front pulley, then around said rear pulley associated with said front pulley and then forwardly so that each of said rear pulleys is acted on by two runs of line and after removal of said seat carriage said apparatus may be mounted vertically for arm exercising, said back support comprising bracing ribs spaced from one another lengthwise, said ribs being provided with longitudinally extending back-supporting means and serving when used on a vertical surface to space the back from said pulleys and Said second tension spring means.
