Physical activity
The Med-A and control groups will be asked to maintain their baseline physical activity pattern, and the WL-A and WL-Med groups will be asked to progress toward achieving 10,000 steps daily. A fitness instructor will engage with participants through the FitBit platform to monitor step counts and to encourage and motivate participants to increase daily steps. The fitness instructor will also create and post social media content (described more below) to provide strategies and motivation around increasing daily steps. The WL-A and WL-Med interventionists will also post challenges to the private Facebook groups to encourage increasing daily steps among their participants.
