An exercise apparatus includes a rigid connector link having a first
portion rotatably connected to a crank, a second portion constrained to
move in reciprocating fashion, and a third portion connected to a foot
support. The resulting assembly links rotation of the crank to movement
of the foot support through a generally elliptical path. The connection
points may be moved relative to one another and/or a supporting frame to
adjust the size, shape, and/or orientation of the path.
