Abstract
An exercise machine has a main frame and a user support frame pivotally mounted relative to the main frame for rotation about a user support pivot axis between start and end positions. The user support frame has at least a primary support and a secondary support for supporting spaced positions on a user's body throughout an exercise movement. A user engagement device is movably mounted relative to the frames for engagement by the user in performing exercises, and an at least partially flexible connecting linkage translates movement of the user engagement device to rotational movement of the user support frame. The connecting linkage includes at least two axially spaced winding portions mounted for rotation about a common cam axis. A load resists movement of at least one of the user support, user engagement device, and connecting linkage.
