No, but olympic powerlifting has professional trainers who know their stuff! these are experts in regards to biomechanics, nutritions, exercise physiology, etc. The chances of being injured are drastically reduced, as opposed to these so called "expert" crossfit trainers.
How cant you see that difference?
To be fair, this is one of those "fish rots from the head down" things that destroys the whole thing. Originally when Crossfit started it was the head guy, Glassman, plus the logistics guys, and then a small group of coaches. Then as it grew things got worse.
They started offering "box gyms" to coaches, then to regular people, provided that they took Crossfit certificate programs, which at the time were run by mostly real coaches. Now here's where a big part of the bad training and programming started, there was overwhelming demand for these courses. Some weeks I remember coaches talking about 20 - 30 grand over a weekend. As the money started to roll in, Glassman, the logistics guys, and a couple of the coaches started to offer courses in everything, and more folks were bought in.
This also started to disrupt much of the actual good training advice that was going on there. As more box gyms were bought, and more courses were sold, more of these new trainers started to ask for time to promote their new businesses, and that's when it really started to get shitty. Instead of training that actually was decent, you got a lot of very lack luster trainers that were allowed main page access because of the money they were pumping into the business of Crossfit.
This also caused a balkanization inside of Crossfit that really did it a diservice. As more of these novice trainers were allowed to program Crossfit, the good ones that were there started to speak out against it, and then were branded traitors if they did. It got so bad that a couple of the coaches had troll accounts that they used to correct the bad info that was being put out on the site.
Also Crossfit has always been brand conscious, and it got a whole lot more aggressive with its censorship and insularity during this time. Even the tiniest perceived insult could develop into a multi - page dressing down on the mainsite, sometimes completely wiping out any reference to a person or product in the Crossfit online universe.
If you look at a timespan between 2006 - 2009, you'll see a pretty large split between the better coaches and Crossfit headquarters. This also helps explain why you'll see that a lot of named better coaches are there now sometimes move on to mostly other things, and sometimes just keep the name for marketing purposes.
There is good Crossfit stuff, but you got to dig for it now.
