8. Readiness, as determined by the Physical Activity Readiness Questionnaire (PAR-Q). If there are any indications that home-based exercise might be unsafe based on PAR-Q, the patient will not be enrolled until confirmation from the patient's provider is received via email and/or phone that they are safe to exercise. Providers do not need to be contacted if patients answer 'yes' to 'Is your doctor currently prescribing any medication for your blood pressure or for a heart condition?

2. 18 years of age or older.
3. Speaks and reads English or Spanish.
4. Consents to complete two online surveys and four 1-on-1 health coaching calls during the 48 week study.
Exclusion Criteria:
EXCLUSION CRITERIA FOR CANCER SURVIVORS:
1. People with potential contraindications to home-based exercise based on the PAR-Q for whom the investigator is unable to obtain physician clearance.
2. ACS guideline score of \> 4 out of 6 at enrollment based on self-reported diet, BMI, and physical activity. Our screening survey will ask participants to report their height and weight; usual intake of foods in the ACS guidelines (e.g., red and processed meat, fruits, vegetables, grains); and the Godin Leisure Time Exercise Survey.
3. Used a physical activity tracker and a diet tracking app for \>= 1 week in the past 3 months; these are components of our digital health tool kit.

5. Scheduled to receive any form of cancer therapy during the study period with the exception of hormonal treatments, which are allowed.
6. History of severe cardiovascular, respiratory or musculoskeletal disease or joint problems that preclude moderate physical activity. Examples include unstable angina, recent myocardial infarction, oxygen-dependent pulmonary disease, and osteoarthritis requiring imminent joint replacement. Moderate arthritis that does not preclude physical activity is not a reason for ineligibility.
7. History of psychiatric disorders that would preclude participation in the study intervention (e.g., untreated major depression or psychosis, substance abuse, severe personality disorder) or prevent the patient from giving informed consent.
8. Participating in another weight loss, physical activity or dietary intervention clinical trial. Co-enrollment in some trials involving pharmacologic therapy is allowed. Participants are also allowed to pursue weight loss and physical activity programs on their own, as long as these programs are not provided as part of a clinical trial.
9. Currently pregnant or trying to become pregnant during the study period.
