This clinical trial studies whether a healthy living intervention (HLI), with or without a physical activity intervention (PAI), helps maintain the ability to exercise, heart health, and quality of life in breast cancer patients who are scheduled to receive chemotherapy treatment. Early detection and enhanced therapies for breast cancer have improved 5-year cancer-related survival rates. Unfortunately, many breast cancer survivors are at high risk for long-term exercise intolerance, decreased heart health, and lower quality of life following chemotherapy. Currently, there are no effective therapies to help patients maintain these areas throughout chemotherapy. The HLI in this study includes virtual health education classes, which provide useful information on topics like proper nutrition, managing stress, and sleep practices. This may help patients understand the importance of living a healthy lifestyle during chemotherapy. The PAI in this study consists of virtual exercise sessions personalized to the needs of the patient, which may make it easier for patients to stay active during chemotherapy. HLI with PAI may be a more effective way to help maintain ability to exercise, heart health, and quality of life in breast cancer patients who are scheduled to receive chemotherapy treatment.
PRIMARY OBJECTIVES: I. To determine if a \> 10% difference exists in change (i.e., 2.06 ml/kg/min difference) in peak oxygen consumption (VO2) from baseline to 24 weeks after initiating cancer treatment between participants receiving the PAI+HLI versus HLI alone. II. To determine if a \> 10% difference in change in left ventricular ejection fraction (LVEF) from baseline (up to ≤ 4 weeks of chemotherapy initiation) to 24 weeks after initiating cancer treatment exists between participants receiving the PAI+HLI versus HLI alone. SECONDARY OBJECTIVES: I. To determine if a \> 10% difference in change in LVEF from baseline to 12 weeks after initiating cancer treatment exists between participants receiving the PAI+HLI versus HLI alone. II. To assess changes in 6-minute walk, health-related quality of life (HRQOL), fatigue, strength, physical activity, sedentary and sitting behaviors and physical function between PAI+HLI and HLI alone groups at baseline to 12 \& 24 weeks after initiating cancer treatment. EXPLORATORY OBJECTIVES: I. We will examine time-dependent changes in traditional and emerging cardiovascular (CV) disease risk factors, including HRQOL, fatigue, chronic psychosocial stress, objectively-assessed physical activity levels, sedentary and sitting behaviors, 6-minute walk distance, self-efficacy for exercise, plasma lipidomics, pro-inflammatory cytokine and fibrosis biomarkers, left ventricular (LV) injury, heart failure (HF), and social determinants of health on exercise capacity and LVEF. II. In a subset (n=50), we will use innovative measures of magnetic resonance imaging (MRI) exercise-associated cardiac output (ExCO) and LV myocardial fibrosis with and without gadolinium contrast to examine mechanisms underlying exercise intolerance and LV dysfunction. OUTLINE: Patients are randomized to 1 of 2 arms. ARM 1: Within three weeks or less of chemotherapy start date, patients access the Trainerize application (app) and attend two virtual pre-chemotherapy exercise sessions over 10-20 minutes each promoting the importance of staying active across the day and throughout treatment and the identification of limitations and familiarization with different types of exercise. Following chemotherapy initiation, patients attend virtual personalized exercise sessions over 20-60 minutes each and organized health workshops over 40 minutes each once a week (QW) during weeks 1-4, once every 2 weeks (Q2W) during weeks 5-16, and once every 4 weeks (Q4W) during weeks 17-24 in the absence of unacceptable toxicity. Patients also receive a Fitbit device, resistance bands, and a loaner tablet, if applicable, on study. Additionally, patients undergo blood sample collection, cardiovascular magnetic resonance imaging (CMR), and cardiopulmonary exercise testing (CPET) on study. Patients may also optionally undergo exercise cardiovascular magnetic resonance imaging (ExeCMR) on study. ARM 2: Within three weeks or less of chemotherapy start date, patients attend a virtual pre-chemotherapy organized health workshop over 60 minutes. Following chemotherapy initiation, patients attend virtual organized health workshops over 60 minutes each QW during weeks 1-4, Q2W during weeks 5-16, and Q4W during weeks 17-24. Patients also receive a loaner tablet, if applicable, on study. Additionally, patients undergo blood sample collection, CMR, and CPET on study. Patients may also optionally undergo ExeCMR on study.

Peak oxygen consumption (VO2)
Will be assessed using cardiopulmonary exercise testing. VO2max, the maximum rate of oxygen consumption measured during incremental exercise, is the gold standard measure of aerobic fitness. It is expressed in milliliters of oxygen consumed per minute per kilogram of body weight (ml/kg/min). Higher VO2max measurements show better function, as it allows one to produce more energy, thereby performing more work.
Time frame: At baseline and 24 weeks
Left ventricular ejection fraction (LVEF)
Will be assessed using cardiac magnetic resonance imaging (CMR). Left ventricular ejection fraction (LVEF) typically refers to the left side of the heart. It shows how much oxygen-rich blood is pumped out of the left ventricle to most of the body's organs with each contraction. It a percentage, ranging from 0-100%. LVEF helps determine the severity of dysfunction on the left side of the heart. Higher values of LVEF represent better heart function.
Time frame: At baseline and 24 weeks
Ejection Fraction (EF)
Will be assessed using cardiac magnetic resonance imaging (CMR). Ejection fraction measures your heart's ability to pump oxygen-rich blood out to your body. In a healthy heart, this is a higher number. A low number means that your heart has difficulty keeping up with your body's needs. It a percentage, ranging from 0-100%. Higher values of EF represent better heart function.
Time frame: At baseline and 12 weeks
6-minute walk test (6MWT) distance
Will be assessed using the Six Minute Walk Test (6MWT). The 6MWT assesses functional exercise capacity, particularly in individuals with cardiopulmonary conditions. The distance walked in 6 minutes on a flat, straight course, typically 30 meters long, is recorded. The distance reflects submaximal (not peak) exercise capacity. The 6MWT is useful for tracking disease progression, assessing rehabilitation outcomes, and evaluating treatment response. Longer distances in meters represents better exercise capacity.
Time frame: At baseline, 12 weeks, and 24 weeks.
Physical functioning
Will be assessed using grip strength (GS) and Short Physical Performance Battery (SPPB). The SPPB measures lower-extremity function on a 0-12 point scale (higher is better; ≤9 indicates risk, ≤8 indicates impairment). Grip strength, measured by dynamometer, is measured in kgf with higher values representing more strength.
Time frame: At baseline, 12 weeks, and 24 weeks
Health-related quality of life
Will be assessed using the The Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-Fatigue) and FACT-Breast. The Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-Fatigue) scale is a 13-item, self-reported questionnaire designed to measure fatigue severity and its impact on daily activities over the past 7 days. Scores range from 0 to 52, with higher scores indicating less fatigue (better quality of life). A score of less than 30 typically indicates severe fatigue. The Functional Assessment of Cancer Therapy-Breast (FACT-B) is a 44-item self-report questionnaire designed to measure quality of life in breast cancer patients, with total scores ranging from 0 to 148. It comprises the 27-item FACT-General (FACT-G) and a 10-item Breast Cancer Subscale (BCS), focusing on physical, social, emotional, and functional well-being.
Time frame: At baseline, 12 weeks, and 24 weeks
Physical activity and sedentary behavior levels
Will be assessed using ActiGraph and ActivPAL accelerometers including mean daily step count. More steps represent more physical activity and less sedentary behavior.
Time frame: At baseline, 12 weeks, and 24 weeks
Physical activity levels
Physical activity levels will be assessed using the Godin Leisure-Time Exercise Questionnaire (GLTEQ), is a 4-item, self-report tool measuring weekly physical activity frequency across three intensities (strenuous, moderate, light) over a 7-day period. It calculates a total leisure score using 9 (strenuous), 5 (moderate), and 3 (light)-with scores typically classifying individuals as active (≥24 units) or insufficiently active (\<24 units). Scores range from 0 with no maximum, higher values represent more physical activity during a week.
Time frame: At baseline, 12 weeks, and 24 weeks
