I agree with Damon. Most of the certs out there do nothing more than enforce and promote policy instead of science. And some certs have even signed deals with soda companies for sponsorship and suddenly became vague about their position on soda. Others, deciding that CrossFit is worth cashing in on, made anti-research recommendations for training to attract the CrossFit crowd. I actually let my NSCA certification lapse this year because I felt like I a hypocrite supporting an organization that, despite their knowledge of the research, continue to stick with 6-decade old, incorrect recommendations for exercise and nutrition.
