A foldable exerciser includes a base member, an upright post, a pair of rail members, and a pair of pedal rods. The base member has a main shaft, and front and rear bars connected transversely to the main shaft. The upright post is connected to the front bar of the base member. The rail members are connected slidably and respectively to the opposed ends of the rear bar. Each of the rail members has front and rear ends, and is disposed perpendicularly to the rear bar on either side of the base member. The rail members are movable between a retracted position and an extended position. Each of the pedal rods is disposed on either side of the base member and has front and rear sections. The rear sections are foldable forwardly relative to the front sections of the pedal rods. The upright post has a lower tube and an upper tube that is foldable downwardly relative to the lower tube.
