This clinical trial studies the feasibility of implementing various adaptive training exercise programs to improve cardiorespiratory fitness in patients after receiving breast cancer treatment. Information from this study may help researchers better understand how to implement adaptive training interventions to improve cardiorespiratory fitness in patients after receiving breast cancer treatment.


OUTLINE: Patients are randomized to the interventional groups or control group.

INTERVENTION GROUPS: Patients are randomized to 1 of 2 interventional arms.

ARM I: Patients participate in aerobic exercise (AE) sessions 3 times per week for 12 weeks. After 12-weeks, non-responders participate in combined AE and resistance exercise (RE) sessions for an additional 12 weeks, while responders continue participating in the AE sessions alone for an additional 12 weeks.

ARM II: Patients participate in RE sessions 3 times per week for 12 weeks. After 12-weeks, non-responders may participate in a further 12-weeks of combined AE and RE sessions, while responders continue participating in the RE sessions alone for an additional 12 weeks.

CONTROL GROUP: After 24 weeks, patients receive a digital copy of the 12-week AE sessions and 12-week RE sessions and an outline of sessions for 24 weeks.
