The 12-week theory-based physical activity intervention will involve mailing participants an exercise manual with health and exercise information (i.e. information about exercising safely, modules related to the social cognitive theory, weekly goal setting worksheets, exercise-tracking logs, etc.), a resistance band, and a standard Omron pedometer. Participants will receive a weekly 30-minute Zoom--based group meetings to discuss different strategies to begin and maintain a consistent exercise routine and access to a social media page to facilitate social support and interaction among the group participants. Participants will be able to join the group if they would like, but it will not be required. Participants will be encouraged to connect with each other to promote social support and social modeling. Lastly participants will receive a weekly exercise video to follow along with on their own time and tailored weekly step goals.

The education group participants will receive the same exercise manual, fitness items, exercise videos, and same weekly tailored step goal as the 12-week intervention group. This group will not have weekly zoom discussions, or be a part of the same social media page as the 12-week intervention group. Instead, the education group will be contacted by research staff once a week via telephone to discuss their manuals and activity for the week, and to ensure they have been safely engaging in exercise. A separate social media page will be created for this group, where pre-existing materials related to physical activity recommendations, benefits, other resources, and more will be shared.

12 week home-based program consisting of: weekly Zoom group chats; exercise videos; free exercise equipment and pedometer; an exercise manual with worksheets to promote increased physical activity; access to a unique group social media page

Participants in the intervention arm will answer Likert-format questions relating to their preference, tolerance and usage of the Zoom-based group meetings to promote physical activity levels. The scale will use a 1-5 rating, with 1 being lowest preference/displeased and 10 being the highest preference/very pleased.

Participants will wear a hip-based pedometer for 7 days at baseline, 12 weeks and 24 weeks.

The Sedentary Behavior Questionnaire (developed by Rosenberg et al., 2010) will be administered at baseline,12 weeks and 24 weeks to assess participants' time spent sitting. Questions relating to sedentary behavior cover both weekday and weekend sitting time, as well as domain-specific sedentary behaviors (i.e. occupational, transportation, and leisure sitting time).Response options for the amount of time engaged in each behavior include: none, 15 minutes or less, 30 minutes, 1 hour, 2 hours, 3 hours, 4 hours, 5 hours, or 6 hours or more. For scoring, the time spent in each behavior is converted into hours, and the hours per day for each item are summed separately for weekdays and weekend days. Higher scores indicate higher amounts of daily sitting time.

Participants in both groups will answer Likert-format questions relating to their preference, usage and perceived helpfulness of the study-specific exercise manual. The scale will use a 1-10 rating, with 1 being lowest preference/displeased and 10 being the highest preference/very pleased.
