ABSTRACT:
A pedal exercise machine with pedals and arm levers operated in conjunction with each other. A base, a front frame and a center frame are coupled to each other and a pair of pedals move upwards and downwards in alternating directions. Pedal links connect the pedals to the base, arm levers couple to the front frame, and lever link units include a first lever link coupled to the corresponding arm lever and a second lever link connecting the first lever link to the corresponding pedal. Subsidiary pedal links connect the pedals to the center frame, a resistance pulley is provided in the center frame, and a crank having crank arms is coupled to the resistance pulley. A first actuating link is coupled to each pedal link at a predetermined angle. A second actuating link is rotatably coupled at both ends to the first actuating link and the corresponding crank arm.
