Abstract
A stair climbing exerciser includes a frame with two links pivotably connected between two lugs on two rails of the frame and two cylinders are respectively connected to the two links and the frame. Each frame is connected to a pedal. An adjusting member is rotatably connected to two bolts extending from the two links so that the two links are pulled toward each other or pushed away from each other by rotating the adjusting member. By this way, the height of the two links and the pedals can be adjusted simultaneously.
