Choose the certifying organization and type of certification you want. Several reputable organizations offer accredited certifications and you can enroll at their websites. Recommended organizations include the National Academy of Sports Medicine and the American Council on Exercise.
If you are interested in teaching group fitness classes, you will need a separate certification. Depending on the organization, you will either take both a written and practical exam, or just a written exam. The Aerobics and Fitness Association of America is among the most common group fitness instructor certifications.
Each organization mails out books, study guides and sample tests. At an extra cost, the International Sports Sciences Association offers local weekend seminars for those who want extra instruction in a classroom setting. These workshops offer the added bonus of networking with potential future employers.
While exam formats differ among organizations, all of them contain practical questions. Be prepared to handle real-life situations, not just multiple-choice questions.
Take the certification exam at an exam center or online, depending on your certifying organization. If you are taking a group fitness certification exam, you may need to lead a small group in a short sample class.
