An exercise apparatus includes a rigid connector link having a first
portion rotatably connected to a respective 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.
