An RFID-based exercise behavior management system is disclosed. The system comprises an RFID tag, a front-end subsystem and a back-end subsystem. The RFID tag contains a unique identification for a participant and is carried by or implanted in the participant whose exercise behavior can be recorded automatically when he is engaging exercise in the field where the front-end subsystem is installed. The backend subsystem enables the recorded exercise behavior to be accessed ubiquitously and to be delivered to related personnel. Thus this invention helps any health promoting agent in realizing and developing trackable exercise programs.
