Many effective interventions or programs are never put into practice. This quasi-experimental study will partner with AME churches in two areas of South Carolina to study how an evidence-based program is put into place by the church. The program, Walk Your Heart to Health, will include training in how churches can modify their practices to support physical activity and healthy eating. Over the five-year study, the investgiators will examine factors that predict the success of putting the program into place, things that help and get in the way of putting the program into place, and how the program can be scaled up to reach even more churches. The investigators will also examine the effect of the program (pre- to post-changes) on walking group member outcomes (physical activity and social cohesion). The investigators expect to work with approximately 26 AME churches for this study.
