I don't do CrossFit and I think CrossFit has many problems. I do not however, think that given proper instruction and supervision, the exercises and rep ranges are particularly problematic. The key point to keep in mind regarding CrossFit is the end goal, the CrossFit games. CrossFitters are not training to be bodybuilders, powerlifters, strongmen, football players or sprinters, they are training to be CrossFitters. If they do a WOD, it is not designed optimally to make them aesthetic or strong, it is designed to improve them in competition. Much like you would not go to an athletic track and complain that the sprinters are not optimally training for a marathon or go to a powerlifting gym and complain the players are not training optimally for bodybuilding, why would you go to a CrossFit gym and complain they aren't training optimally for any number of other forms of competition that involve weight? That said, it should be clear to people when they sign up to a CrossFit gym that this is indeed the case and other benefits are side effects.
