Abstract
The present invention relates to a body weight driven treadmill, and when the exerciser steps on the treadmill, the exerciser's body weight acts as a loading to tilt the pedal platform upward from the rear back of the treadmill, since the base of the treadmill has a front supporting rod and a rear supporting rod, wherein the radius of the front supporting rod is slightly smaller than that of the rear supporting rod, and the points of contact tangential to the ground are different. Such arrangement can slightly tilt the exerciser's body forward, until it reaches equilibrium and a stable position. When the treadmill is stepped by our legs alternately, the pressing foot will tilt forward, and twist the exerciser's waist. Such body weight driven treadmill is a simple and easy-to-assemble structure and does not occupy much space.
