Twenty participants (10 intervention and 10 control) will be enrolled. To avoid enrolling higher risk subjects that require in-person CR supervision, the investigators will exclude subjects with a history of heart failure, cardiomyopathy, severe valvular disease or rhythm disturbances requiring cardioversion. Patients with defibrillators and those unable to consent, speak English, comprehend study procedures, cycle on a stationary bike, perform a treadmill test, or access the internet from home will be excluded.
