ABSTRACT:
A twisting device for a climbing exerciser includes a rotatable member rotatably mounted on a cylindrical tube on the base and the rotatable member includes two flanges so that two connection plates connected with two pedals are respectively connected between the two flanges. The rotatable member is connected with a handlebar stem so that when the user operates the pedals alternatively, the two connection plates rotate the rotatable member reciprocally to drive the handlebar stem to twist about an axis of the handlebar stem.
