An elliptical exerciser includes a base, a body, a transmission device, an adjustable upright post, a pair of handles and two foot pedal rods. The post is composed of an upper tube which is retractably inserted in a lower tube. Two respective mediate portions of the two handles are connected to two sides of the upper tube. Two ends of each foot pedal are respectively connected to a lower end of the handle and the transmission device. The swinging of the handles drives the foot pedal rods and the transmission device rotates. The positions of elliptical trace of the pedal rods are adjusted by adjusting the upper tube upward or downward relative to the lower tube so as to simulate uphill hiking and downhill hiking and exercise different parts of muscles.
