Abstract: An exercise machine includes a static disk that is fixed in place and a dynamic disk that both rotates about its axis and revolves about the static disk. The static disk and the dynamic disk are mechanically coupled in a manner that provides a constant angular relationship between the rotation of the dynamic disk about its axis and the revolution of that axis about the axis of the static disk. The machine further includes a rotating member supported by a static pivot axis and a crank axle to which the dynamic disk is fixed. The crank axle is rotated by a crank and the rotating member imposes a fixed distance between the crank axle and the static pivot axis. The foot pedal member is pivotally supported at a distal end of the crank so that rotation of the crank causes the foot pedal to follow a generally elliptical path.
