While living in Peru in the last 2 years, I became certified to teach a style of cardio kickboxing developed there. I am back in the US and would like to teach kickboxing here but have found that I need an additional certification as a group exercise instructor. This is a little frustrating because I have my bachelors in kinesiology, my masters in athletic training, and my doctorate in physical therapy. I work full time as a physical therapist, and I just want to teach once or twice a week because the class is really fun and I want to share it with others. I am willing to get the certification but because of my background and the cost, I want to know which is the BEST cert for group exercise instructors. I want to be able to do this once, learn something, and be able to use it at any gym. Thanks!!
ACE, ACSM or AFAA depending on which you want to choose as the others have listed above the differences between them. But I would first check with the gyms you want to teach at to ensure they accept that certification or if they have a preference. Some even sponser certifications and may have one coming up that you can join. Many gyms hire people who have taken the certification class through them.
