Semi recumbent exerciser

An exerciser having two linkages each with a member and a projecting extension. A distal end of each of the extensions travels in an oblong orbital path while one end of the member travels in a circular, orbital path and the other end travels in a reciprocating manner back and forth. This other end has wheels arranged to roll along a track without sliding. The exerciser has foot supports each attached to an associated one of the distal ends of the extensions and has arms that move in a reciprocating manner opposite each other. Provision is made to ensure that the arms and foot supports move through dead spots at the ends of their respective courses of travel. The arms and legs traverse respective distances when moving back and forth that are substantially the same in dimension.
