A successive sliding exerciser includes a beam, a sliding part which is installed in the beam and is able to slide between two ends of the beam, and two upholders to support the beam on two ends. Each upholder has a stepping slot with two platforms of different height. When using this exerciser, a user grabs the sliding part and slides from the higher end to the lower end. Upon reaching the lower end, the beam is lifted backward and is placed on the higher platform, the other end automatically falls to the lower platform. One end to the other, the two ends of the beam switch their positions of lower end and higher end. Therefore, the user is able to slide back, and the exercising action can continue back and forth.
