Here's a follow-up article to the "Why I don't do Crossfit" article that had so many Crossfitters panties in a wod (like what I did there?). Ms. Simmons presents the relevant science fairly and explains it pretty well. I wouldn't be surprised if Crossfit Inc will try to sue her as well since Glassman, et al cannot stand to have scientific refutation of their practices.
