In this study, we will implement a pilot project of using activity tracker (i.e., Fitbit) with phase III CR clients. The study will record the clients' daily steps and sleep patterns for 8 consecutive weeks in natural settings. Two specific aims are identified for this project:~Develop an intervention protocol using mHealth to promote Phase III CR clients' self-monitoring of PA.~Examine the efficacy of the intervention on clients' PA, sleep patterns, functional capacity and QoL.
