Evaluating Mechanisms of Action of Adaptive Goal-Setting for Physical Activity

Over video-call, participants will receive educational content on safely increasing their levels of physical activity (e.g., selecting an appropriate form of exercise, minimizing health risks, the importance of planning), will receive daily text messages (see arm descriptions) for six weeks and complete a 10-15 minute check-in call at the 3-week point of the intervention to assess compliance with daily step goals as well as to help problem-solve barriers to compliance.
