Abstract
An exercise apparatus comprises a frame, a left foot link supporting a left foot pad, a right foot link supporting a right foot pad in a left foot link supporting a left foot pad. The right foot pad is linked to the left foot pad so as to synchronously move out of phase with the left foot pad through an elliptical path having an adjustable step height and an adjustable stride length. An adjustment synchronizer is operably coupled to the left foot link and the right foot link to synchronously adjust both the step height and the stride length of the elliptical path.
