Patients will be given an exercise prescription provided by a certified exercise physiologist.~The exercise prescription will change each week based on refreshed data from the prior week.~Instructional videos for each exercise are provided in the app. Patients will not be told to perform the exercise at a particular time. Instead they will be asked to complete a certain amount of exercise per week at whatever time is convenient for them. Patients randomized to remote CR will also receive App based reminders to take their medications, resources to guide healthy eating habits, and other behavioral health advice as is done as standard of care in both remote based and clinic based CR."
