Abstract
An exercise apparatus links rotation of left and right cranks to elliptical movement of left and right foot supporting members. The foot supporting members include left and right foot platforms that travel through space defined between the left and right cranks. Rollers on the cranks allow the foot supporting members to translate relative to the cranks, and amplified drawbar/rocket link arrangements determine the extent of the translation.
