Also, to say that real athletes aren't and wont do crossfit is just factually wrong. Lorenzo Neil does crossfit. So does Ladanian Thomlinson, Knowshawn Mareno, and another guy that maybe you have heard of, Ray Lewis. UFC fighters BJ Penn,chuck lidell and Matt Hughes. NHL star Ethan Moreau. As well as alot of people like police SWAT teams, firefighters and some Military special forces units. And remember, crossfit has only been around for about 10 years and has only started to get popular in the last maybe 3. So you will see more and more elite athletes doing crossfit in the near fututre.
See here is the thing. Our aim is to do functional movements. If you go to the gym and do chest, traps and arms 3 times a week you will have a big upper body but so what. It does no real good. All it means is you can bench press alot of weight. It has no actual value in the real world. With our workouts you work multiple joints all the time, and alot of it involes core work which helps your body do everything better. And i mean actual real world stuff. Alot of machine weights, cable bicept curls and many other gym exercises are designed by engineers that will make muscles bigger but those movements dont generally exists outside the gym.
