It is the purpose of this clinical trial to examine the feasibility and acceptability of a brief online physical activity group (incorporating motivational interviewing) for UK women who are currently experiencing peri- or post-menopausal symptoms and working full-time. To measure feasibility and acceptability, the following will be examined: 1. The ease that participants were recruited; 2. The proportion of participants that remained in the online physical activity group (attending at least half of the sessions); 3. The proportion of participants that remained in the study; 4. How acceptable the participants find the online physical activity group; 5. Whether there is a preliminary indications that the online physical activity group may increase participant activity levels. Once provided informed consent, all participants will be randomly allocated into either the online physical activity group (intervention arm) or the control group. Participants will be asked to complete outcome measures at the same four timepoints, as well as completing a weekly physical activity log.
