The aim of this study is to assess the feasibility and acceptability (e.g., enrollment, adherence, retention, acceptability of procedures and interventions) of a pilot factorial study design that will help elucidate components of mind-body exercise interventions. The study involves completing a walking program, a mindful attention program, a walking program that includes mindful attention, or no program at all. A "pilot" study is a smaller study that helps researchers to understand whether the study design can be carried out and what participants think about the study.
