With such a topic so broad we truly try to cover the basics from all angles in this group. Nothing too big or too small. Nutrition is as significant if not more as exercise is to reaching your goals so learn all you can.
I did one self-paced course through International Sports Science Association (www.issaonline.com). They give you 2 years to complete the program, and even though its self paced and open book test, it is challenging, but I really learned a lot. I am beginning my second course in a few weeks. I recommend it.
