Patent ID: 7699758

Claim:
Exercise apparatus comprising: a frame; movement means mounted on the frame and moveable by a user in opposite directions; resistance means; a transmission for coupling input rotational movement of a transmission input to the resistance means in a manner to provide a different resistance to rotation of the transmission input depending upon the direction of rotation of the transmission input, the resistance means resisting rotational movement of the transmission input in one rotational direction to a greater extent than it resists rotational movement of the transmission input in the opposite rotational direction; and means coupling the movement means to the transmission input and converting movement of the movement means into rotational movement applied to the input of the transmission, movement of the movement means in one direction creating rotational movement of the transmission input in one direction and movement of the movement means in the opposite direction creating rotational movement of the transmission input in the opposite direction, said movement means including a carriage mounted on a track for movement back and forth along the track, the movement means secured to and extending from the carriage; and a belt secured to the carriage and to the transmission input whereby movement of the carriage causes movement of the belt which, in turn, causes rotational movement of the transmission input.
