Technology-Supported Physical Activity Intervention for Metastatic Breast Cancer Survivors: Fit2ThriveMB

The Fit2thriveMB app will encourage participants to increase their physical activity. Participants will be provided with educational information on physical activity and effective behavior change strategies for incorporating more physical activity into their daily lives to increase their step count. Participants will be prompted each morning to report the intensity of their symptom burden (0 to 10). Based on their symptom rating and their previous day's step counts, participants will be provided with three different options or levels of goals for that day to either increase or decrease 10-20% or remain constant.

The Fitbit measures PA intensity, steps, and heart rate and syncs directly with the smartphone and will automatically sync with the Fit2ThriveMB app and provide Fitbit data to the study team in real-time.

Participants will receive weekly coaching calls which will: a) provide feedback on the previous week's symptom burden and progress on PA goals; b) review personalized goals and strategies for increasing PA for the next week; c) provide instruction on effective behavioral change techniques

Participants will receive weekly calls that will cover health and well-being topics for instance: symptom and stress management, healthy diet, hydration, sun safety, sleep hygiene, and meditation.
