You are able to teach classes that you design.
So, for example, you could teach a general cardio class, a weight training class with dumbells or tubing, a circuit class, etc. You will have been trained how to warm someone up properly, how to give them a cardiovascular, strength, interval or circuit workout, how to cool them down, and how to stretch them out. What you do from there depends on where you want to work and if you want to design your own format or pay for someone else’s.
When I started in the fitness industry, a basic certification was all we needed. Now, there’s more pressure to get licensed in a branded format. If you decide to align yourself with a branded format, check to ensure that you really believe in it before you license it. I work at a gym that has hosted quite a few trainings and have seen pros and cons to about a dozen formats. Some of them, I’ve decided to teach. Others, after I took them, I wasn’t interested in teaching.
Perhaps do some informational interviews with fitness coordinators in your area. See what they like, what their gyms need and appreciate. Of that, what interests you the most? What would you be good at? What are the fees? How flexible are the requirements?
Lost and lots of choices! Best wishes!
I also have AFAA Primary Group Exercise certification, and it may depend on where you decide to work. Like Nancy, when I started teaching classes years ago, a basic certification was all you needed. Some classes that I have both designed and have been teaching for YEARS now have “specialty” certifications. Some programs are good, and some just want your money.
You may want to get your basic cert and see where it takes you—both my group exercise and personal training certs have served me very well. As Nancy mentioned, do some research on programs in your area. I am also a believer in informational interviews–you never know the connections and opportunities that may arise from them.
Good luck and welcome to the fitness industry!
