Abstract

A multi-station exercise machine in one embodiment comprises at least two exercise stations for performing different exercises, at least one of the stations having a main frame, a user support frame pivotally associated with the main frame, a user engagement device movably mounted on one of the frames for actuating by a user in order to perform an exercise, and a connecting linkage which links movement of the user engagement device to movement of the user support. A load provides resistance to movement of the user support frame, user engagement device and/or connecting linkage. The connecting linkage, user support pivot, and user engagement device mount are arranged so that movement of the user engagement device results in self-aligning movement of the user support. The other station may have a fixed user support or a moving user support.
