Crossfit has come a long way recently with some of its form issues. They way that they're trying to legitimize themselves as a "sport" with the Cross Fit Games, they have taken steps to make the form "standardized" (ala powerlifting standards) and what those kids are doing IS NOT crossfit.
Do I disagree with a lot of their programing? Yeah. Do I think most crossfitters are the fitness industries equivalent to Jim Jones cult followers? haha yeah... but its not all bad.
That being said, I'm not a crossfit guy but I've done some of their workouts and respect it. Its just another tool for your toolbag so to speak.
