To become a fitness instructor, certain qualifications are typically required. The specific requirements may vary depending on the organization or gym you wish to work for, but generally, you will need at least a high school diploma or GED equivalent. Many employers also prefer candidates who have completed some form of post-secondary education related to exercise science, kinesiology, or physical education. Additionally, most fitness instructors need to obtain a certification from a reputable organization such as the American Council on Exercise (ACE), National Academy of Sports Medicine (NASM), or the Aerobics and Fitness Association of America (AFAA). These certifications typically involve completing an exam that tests knowledge and understanding of exercise techniques, physiology, anatomy, nutrition, and client safety.
