They will have to participate in a 6-month personalized non-supervised exercise program consisting of 3 weekly sessions of 20 min to 1-hr of moderate-to-vigorous physical activity (≥3 METs): 2 sessions of brisk walking and 1 session of muscle strengthening. Women should wear the wristband daily to track their number of steps (automatic Bluetooth synchronization to the application). Duration and intensity of sessions and target number of daily steps will progressively increase (+15% up to 10,000 steps) to place the patients in a progression dynamic. Women will receive phone-based follow-up at 1 week, 2 months, and 4 months.
