This study will last 12 weeks. Participants will be randomly assigned to one of two groups. Group 1 participants will take part in 30 minutes total of self-selected lifestyle physical activity throughout the day, 5 to 7 days per week. Twice a month, they will attend group sessions designed to help participants develop and maintain a more physically active lifestyle. Goal setting, self-monitoring, and pain management will be discussed at these sessions. Group 2 participants will attend monthly FM educational sessions, which will focus on understanding the symptoms of FM, learning to manage pain and fatigue, and developing self-help strategies.
