Overview
The study will use a cross-sectional study design with a follow-up 2-arm randomized controlled trial with that has assessments at baseline, post-intervention (i.e., Week 12), and 3-months post-intervention (i.e., Week 24). The 2 arms are the 12-week intervention and waitlist control among 30 Black breast cancer survivors
Description
14AUG2025- The sample size was updated, and the questionnaire was split into 2 questionnaires, as a planned solution in response to a low accrual
28OCT2025- Amendment was processed to update design and intervention items. The exercise threshold was changed from a 1-repeition maximum (1RM) to a 5-repeptition maximum (5RM). Since the intervention includes functional exercises, so we elected to use a functional strength (5RM) outcome rather than a maximal strength outcome (1RM) to better align with the intervention. The control condition was changed to a waitlist design. A waitlist control is more engaging, and there is a higher likelihood of retaining control participants.

- metastatic disease;
- medical reason that precludes them from increasing current exercise levels;
