The Athletics and Fitness Association of America (AFAA) has led the way in certifying group and personal trainers for over 30 years. AFAA released the first nationally standardized guidelines for fitness professionals, and has prepared over 350,000 fitness instructors and trainers in 73 countries. Our vision isn’t to just change bodies — but to advance the lives of instructors and trainers, and those they guide through their own personal fitness journeys.
