I'm not a gym person (I maintain a very active lifestyle---biking, walking, sports). What I am is a 40 year old woman who is always thought to be 25 or so and who is constantly asked for my "secrets". Any advice what certification I should get? I have a BA in a social science and see that some certs require a degree. I aim to take private clients and to become a speaker, teaching fitness and healthy whole foods based eating and food preparation. (I'm currently taking courses in holistic nutrition.) I would appreciate any advice regarding whether or not a personal fitness trainer certification would be right for me. Thank you.
