An exerciser includes a pair of tracks having a rear portion rotatably supported on a base with a pair of cranks, a pair of bars pivotally secured to a front portion of the base, a pair of levers each having a foot support and each having a front portion pivotally secured to the bars and each having a rear end slidably engaged on the tracks, for allowing the foot supports to be moved in a reciprocating action. The tracks are movably supported on the front portion of the base without being elevated, such that the foot supports may be lowered and stably supported on the base.
