All participants will be randomly assigned a physical activity goal (45 min/week, 90 min/week, or 150 min/week). To help participants achieve goals, they will receive a 6 month program which includes the Arthritis Foundation's Walk With Ease Guidebook, behavioral lessons, a Fitbit, and monthly coaching calls. Participants may also receive additional calls, texts, or emails if they are struggling to meet their physical activity goals.
