Abstract: A multipurpose body exerciser includes an I-shaped bottom block mated with a vertical main frame and a support frame for mounting of a seat and a back cushion on the main frame. The exerciser further includes two elongated foot-pedals disposed at both sides of the vertical main frame, each respectively suspended by a steel cord hung on a pulley block to provide the foot-pedals for training of the legs. Two vertical rocker rods are provided on opposing sides of the vertical main frame for training of the arms. The foot-pedals and the rocker rods are adjustable by associated hydraulic cylinders, to provide a predetermined tension for providing the best performance appropriate to a user's condition. The whole structure may be divided into three independent portions for convenient transportation or packaging to minimize space requirements.
