Abstract
An exercise machine includes a rocker and a weight bearing frame pivotally interconnected with the rocker. The rocker and weight bearing frame are each pivotally mounted on a support frame or base. The weight bearing frame opposes movement of the rocker when the rocker moves in one direction and assists movement of the rocker when the rocker moves in another direction. The rocker can move from an upright orientation to a second orientation in which the rocker is canted below horizontal.
