I am actually trying to make a career change to become a personal trainer and fitness instructor. I'm working on getting my primary group exercise certification from AFAA and then a personal trainer certification. After I have those 2 under my belt I am going for a wellness coach certification. I've always wanted to do something in the fitness industry but never pursued it. Now I'm in my late 20s and thinking about starting a family in the next few years, so if I'm going to take a chance and try to change careers, I think now is the time to do it.
If it is a passion of yours I think you should definitely go for it! It's good to have a diverse background so you'll have options when it comes to choosing a career. Good luck!!
