Disclosure herein is related to a personal exercise prompting method, a system, and an exercise platform thereof. In the method, a physiological signal trend related to an exerciser can be instantly predicted according to a personal exercise model associated with the exerciser. While the physiological signal trend is compared with the signal trend of an exercise plan, a prompting signal is generated based on the comparison. The prompting signal may be guidance voice for guiding the exerciser using a sport mode. In one embodiment, the exerciser may wear a device with sensor for sensing physiological signals when the exerciser is in exercise. The personal exercise model is established or updated according to the sensed physiological signals. In the platform, a wearable device may be included, or associated with a mobile device. The mentioned personal exercise mode and the exercise plane may be loaded from a cloud system.一種隨身運動提示方法、系統與一運動平台,在隨身運動提示方法中,根據一運動者的個人化運動模型即時預測運動時的生理訊號趨勢,之後根據生理訊號趨勢與一運動計畫的訊號趨勢的比對結果產生提示訊號,例如為引導運動者運動方式的引導語音。根據實施例之一,運動者可以配戴具有感測器的裝置,能感測運動者運動時的生理訊號,系統再根據運動者的生理訊號建立或更新此運動者的個人化運動模型。相關的設備可以為一穿戴式裝置,或可與一行動裝置配合,並自一雲端系統載入個人化運動模型以及運動計畫。S801‧‧‧根據個人化運動模型預測生理訊號趨勢S803‧‧‧比對運動計畫的訊號趨勢S805‧‧‧產生提示訊號
