Claim Text:
1. A method of detecting and prompting a human lower limbs stepping motion, applied to an exercise machine with pedals installed to both left and right sides of the exercise machine respectively, for detecting a pedaling force when an exerciser steps on the pedals, and the method comprising the steps of: installing at least one front force sensor and at least one rear force sensor to each pedal for detecting the pedaling force; detecting the pedaling force by the at least one front force sensor and the at least one rear force sensor installed at each pedal to generate at least one electric signal when the feet of the exerciser's legs step on the pedals on both left and right sides of the exercise machine; transmitting the at least one electric signal to a control unit and converting the electric signal into a pedaling force value; comparing whether the pedaling force value or a difference value of the pedaling force values detected by the at least one front force sensor and the at least one rear force sensor is equal to a predetermined value in the control unit by the control unit; and prompting a message if the pedaling force value or the difference value is not equal to the predetermined value; wherein each pedal includes the at least one front force sensor installed at the front of the pedal and the at least one rear force sensor installed at the rear of the pedal, and the control unit compares whether the difference value of the pedaling forces detected by the at least one front force sensor and at least one rear force sensor is equal to the predetermined value, and a message is prompted if the difference value is not equal to the predetermined value.
