NASM, Ace, ISSA and other basic nutrition courses seems to be very basic. I need to find a course that is more advanced for someone who already is very experienced helping clients with nutrition. I don’t have a basic nutrition cert. but I don’t want to be wasting my time paying for, and studying things I already know. Any suggestions on how to approach this situation?
since you say that you are very experienced helping your clients with nutrition, I was wondering whether you are already a Registered Dietitian. But re-reading your question, you mention that you do not have a basic certification which leads me to believe that you have acquired your knowledge outside of formal settings.
While there is nothing wrong with that by itself, this may limit you taking things a step further. Since giving nutrition advice beyond the generic recommendations is outside the scope of a personal trainer, I would suggest that you pursue becoming an RD. From that point on, you can pursue many advanced degrees.
