Breast Cancer Resiliency Through Exercise Program (B-REP)

Inclusion Criteria: Women will be eligible if they meet the following criteria: * self-identify as Black or African American or Afro-Latina/e; * are ≥18 years old; * have a confirmed diagnosis of breast cancer, Stage I to IIIA; * have completed primary active treatment (i.e., surgery, chemotherapy, and radiation) within 5 years prior to study start where concomitant hormonal therapy is acceptable; * are not meeting current cancer-specific resistance exercise guidelines of ≥ 2 times per week; and * are able to speak and understand English. Exclusion Criteria: * metastatic disease; * medical reason that precludes them from increasing current exercise levels; * planned elective surgery during study period; * pregnant or plans to become pregnant during the study period; * plans to move out of United States during the study period; (the rationale for this exclusion is that it will be difficult to conduct the in-person assessments if a participant leaves the United States); * current enrollment in another exercise trial; and/or * inability to pass exercise pre-screening or receive physician consent to increase current physical activity levels.
