The problem with Crossfit is that a lot of the people running those gyms took a week long class to be get their level 1 training and thats all they require to be an affiliate. Some of these classes are run by instructors who have no formal training in anything to do with the our sport whatsoever. There are 2 crossfit gyms in our town one is run by 4 girls who came into some money from another business they ran and they are now running this huge facility and it's almost exactly like that video, the other is a husband and wife team that are both OLY lifters and the husband was pretty high up in MMA for awhile, both have masters degrees related to training and their gym is pretty badass. So I won't paint crossfit with to broad of a brush but some of the places and pretty ridiculous.
