Abstract: The present invention provides an exercise device for exercising at least two groups of muscles. The device includes a first subframe supporting body support members including a foot rest and seat. A second subframe is operably coupled to the first subframe by a joint having two axes of rotation and internal stops for controlling the rotation about both axes. A back rest is carried by the second subframe. The back rest is movable in generally opposite directions to exercise the two groups of muscles. Elastomeric resistance elements are selectively and operably coupled across the joint.
