Inclusion Criteria

    1. T2D. Eligible patients will meet American Diabetes Association (ADA) criteria for T2D (e.g., HbA1c [A1C] ?6.5%, fasting glucose ?126 mg/d), with diagnosis confirmed by their diabetes clinician and/or medical record review. Patients with well-controlled T2D will be included if they have low physical activity because inactivity still puts them at risk for complications. 2. Low physical activity. Low physical activity will be defined as ?150 minutes/week of MVPA (corresponding to ADA recommendations for moderate or greater intensity aerobic physical activity). Physical activity will be measured using a brief questionnaire adapted from the International Physical Activity Questionnaire (IPAQ) which has been used and validated in medical cohorts. 3. Prescribed a non-insulin glucose-lowering drug or choosing lifestyle interventions (diet and exercise) to manage T2D.

Exclusion Criteria

    1. Cognitive impairment precluding consent or meaningful participation. 2. Lack of phone availability. 3. Inability to read/write in English. 4. Additional medical conditions (e.g., severe arthritis) that preclude physical activity.
