Group fitness instructors work with several clients at a time. Instructors develop and lead classes in areas like cardiovascular, abs, strength, aerobics, spinning, and dance. To be a group fitness instructor you need to be able to pay attention to the details of teaching proper form and alignment for each exercise while being comfortable in front of large groups.
The first step in becoming a group fitness instructor is to get your CPR/AED certification. CPR is short for CardioPulminary Resuscitation and AED stands for Automatic External Defibrillator.
You can find a CPR/AED certification class in your area by visiting the American Red Cross website to search for instructors in your area. The 5 hour course can be completed in a single afternoon and usually costs around $60-$70.
Once you are a certified life saver you will want to get your Group Fitness Instructor Certification. Two major organizations offer group fitness instructor certifications as well as personal trainer certifications: ACE (American Council on Exercise) and AFAA (Aerobics and Fitness Association of America).
Different gyms and health clubs require different certifications for their instructors so be certain to ask your gym of choice which certification they prefer. ACE certification is more widely recognized but generally harder to complete. Certification in both ACE and AFAA increases your value and marketability as a fitness instructor.
