The goal of this study is to collect wearable sensor data that the investigators hypothesize will be useful in future algorithm development for monitoring recovering of participants enrolled in cardiac rehabilitation programs. Participants will be provided one or more smartwatches and/or smart rings to wear during a 14 week study which includes 2 weeks of baseline data collection and a 12-week, 36-session cardiac rehabilitation program. They will capture a pre-assessment 6 minute walk tests and a post-assessment 6 minute walk test. They will otherwise conduct standard cardiac rehabilitation program procedures and our sensors will capture data and sleep information throughout the study period.
