This study plans to learn more about psychosocial factors that contribute to adopting physical activity. The goal of this study is to improve upon existing theories of behavior change in order to help other people become more physically active.

The purpose of this study is to examine the relationship between personal life meaning and purpose and physical activity maintenance in a group of previously sedentary adults starting new exercise programs. Participants complete questionnaires at baseline, 4 weeks, and 12 weeks after starting an exercise program. Participants are randomly assigned to complete questionnaires about daily meaning, mood, and activity for the first 4 weeks or to complete 8 random questionnaires about daily activities over the first 4 weeks. It is hypothesized that personal life meaning and purpose will be related to greater exercise participation at 12 weeks.
