Abstract
Disclosed is a structure of climbing exerciser, which comprises a freewheel mounted on the frame body thereof and driven to alternatively rotate forward and backward by two driving cords which are connected between the freewheel and two pedals which are mounted on the frame body for pedaling of feet. A retarding belt is mounted on the freewheel with one end secured to the frame body via a spring and with the opposite end connected to a tension regulating device through a steel rope so that the binding force of the retarding belt on the freewheel can be adjusted according to one's condition.
