Transforming Recovery Through Exercise and Community

The primary aim of this study is to develop a feasible, acceptable, and effective multilevel physical activity (PA) intervention that addresses both individual and interpersonal factors that can be easily scalable and delivered in the context of a methadone clinic. To do so, the investigators will train methadone maintenance treatment (MMT) patients who are already engaging in PA at public health recommended levels to deliver a group-based PA intervention to physically inactive MMT patients at a large community-based methadone clinic. Through the development of interpersonal relationships and social support, the investigators expect that MMT peers who have successfully navigated challenges associated with PA in this population (i.e. depression, smoking, triggers for drug use in environment) will help physically inactive MMT patients increase self-efficacy and motivation for initiating and sustaining PA.
