What are fitness instructor certification requirements?

There is not a specific type of fitness instructor certification that every instructor has to get. In order to get a job as a fitness instructor, you will generally have to get one of two certifications that are available. You can get a fitness instructor certification from the Aerobics and Fitness Association of America. You can also get a certification from the American Council on Exercise. In order to obtain these certifications, you will have to undergo a written exam as well as a physical exam on several fitness-related topics.
