• Have undergone a lumpectomy or mastectomy.
• Have received and completed neoadjuvant or adjuvant chemotherapy and/or radiation therapy within the past 12 months.
• Speak English or Spanish

• Able to initiate a supervised exercise program (free from any cardiovascular, respiratory or musculoskeletal disease or joint problems that preclude moderate physical activity)
• Free from history of chronic disease including uncontrolled diabetes, hypertension or thyroid disease
• Have not experienced a weight reduction ≥10% within the past 6 months
• Currently participate in less than 60 minutes of structured exercise/week
• No planned reconstructive surgery with flap repair during trial and follow-up period
• May use adjuvant endocrine therapy if use will be continued for duration of study intervention
• Does not smoke (no smoking during previous 12 months)
• Willing to travel to Dana-Farber Cancer Institute for necessary data collection
• Ability to understand and the willingness to sign a written informed consent document.

You may not qualify if…

• Patients should not have any uncontrolled illness including ongoing or active infection, uncontrolled diabetes, hypertension or thyroid disease; women using Metformin to manage diabetes will be excluded from the trial
• Patients may not be receiving any other investigational agents, or concurrent biological, chemotherapy, or radiation therapy
• Patients with other active malignancies are ineligible for this study.

• Has not completed surgery, chemotherapy, or radiation treatment associated with their diagnosis
• History of any musculoskeletal, cardiorespiratory or neurological diseases that preclude the participation in exercise
