ABSTRACT:
Exercise machine which combines an up and down leg motion with a back and forth arm motion, with the arms and legs each providing resistance to the movement of the other. A pair of foot levers is pivotally mounted on a frame for up and down movement in a generally vertical direction, with pedals carried by the foot levers for engagement by the feet of a person using the machine. A pair of vertically extending hand levers is pivotally mounted on the frame for back and forth movement in a generally horizontal direction, with hand grips carried by the hand levers for engagement by the hands of the person using the machine. A pair of connecting rods interconnect the foot levers and the hand levers for movement in concert so that the arms and the legs of the person using the machine can resist movement of each other. Additional resistance is provided by a strap which is trained about a pulley and connected to the levers in one of the two pairs, with a brake for resisting rotation of the pulley.
