An exercise mechanism includes a beam and a pair of tracks disposed on a base. A pair of foot supports each has a rear end slidably engaged on the tracks and each has a front end pivotally coupled to a lower end of a pair of handles. The handles each has an upper portion pivotally coupled to the beam by a link and each includes a lower middle portion coupled to the beam by a crank for allowing the lower middle portions of the handles to be moved in a circular reciprocating action. The foot supports may be moved forward and rearward by the handles.
