Just wondering here -- Isn't crossfit different depending on where you go? I believe it was invented by some European guy... who did stuff with kettlebells. And most of those exercises are good. I think the American variant is the one that's dangerous. (Or am I misinformed here?)

Don't think it's a geographical split. Crossfit is great if you have really well-informed trainers that put a strong emphasis on getting form and movements correct. Unfortunately there are significant numbers of trainers that do not have the qualifications to be teaching and they put people at serious risk of injury (and end up creating ridiculous exercises for the internet to make fun of).

kipping is fucking hilarious

> “millions of individual adherents“ Is Crossfit a cult? At first I thought the article was a parody or something

It has become a cult. I personally have no problem with people lifting and motivating each other and CrossFit was originally quite good, especially the competitive athletes. But now a days it’s become a huge cult where it’s all about people motivating each other to see how many reps of a certain exercise a person can do while completely throwing the form out of the window. Couple of my friends are in sports medicine…

To be fair, the growing numbers of CrossFit athletes alone could describe the growing numbers of injuries. If e.g. 10x as many people do CrossFit than do handball, they will account for a majority of injuries.

If you've ever been an athlete, and have spent 30 seconds watching crossfit - it becomes obvious the goal is to see how dumb of an "exercise" you can do before getting hurt. There are two type of crossfitters - those who have gotten a permanent and serious injury, and those who are going to get one.

I can't verify the quality of these studies but it seems that injury rates per 1000 active hours of crossfit at 0.27 - 0.74 [1] are significantly lower than more common sports such as running at 2.9 - 4.4 and basketball at 6.3 - 12.9 [2] [1] https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6201188/ [2] http://bionics.seas.ucla.edu/education/Rowing/Injury_2004_01...

Last I checked there wasn’t CrossFit for basketball. You should compare apples to apples. How does it stack up against (trained) non-CrossFit weight training?

Judging by how those idiots abuse gym equipment I’d expect poorly, but prove me wrong.

Wow I had heard Crossfit was a bit of an obsession for some people and a quirky approach to fitness, but I had no idea their official spiel was this level of paranoia - attacking academia as an unholy alliance of the establishment? > The voluntary CrossFit community of 15,000 affiliates and millions of individual adherents stands steadfastly and often alone against an unholy alliance of academia, government, and mult…

If they had simply said "Facebook does not respect its users and is psychologically unhealthy; we're out" then I would've been pretty nonchalant. What a weird and unnecessary rant.

Before I clicked the link I thought "I bet they got facebook warnings for some junk posts, but they'll play leaving facebook off as a moral decision." But I was surprised to be so wrong. With phrases like "corrupt academic organizations" they aren't even even trying to hide their culture-wide embrace of pseudosciences.

Don't even start me on Uncle Rhabdo, a cartoon character that CrossFit used to say "if you weren't causing your body damage, you weren't working out hard enough". Rhabdomyolisis is a serious injury with potentially life threatening or life lasting consequences. The idea that a fitness fad would make light of it so astound me.

I think you're thinking of Pavel Tsatsouline that promoted the kettlebell in the west. Crossfit came much later.

Actions like this are an annoying distraction. Crossfit HQ is kind of a nuthouse. The Crossfit program is truly wonderful as long as you always use proper form. If you can't use proper form on a rep, don't do the rep. It's that simple. I have been doing Crossfit for a year and haven't seen any significant injuries. But my gym emphasizes proper form over numbers. Some gyms ensure people use proper form, some don't. Cr…

> If you can't use proper form on a rep, don't do the rep. It's that simple. This is sorta disingenuous. A layman can't tell if they're doing an exercise correctly without instruction, and you can do something correctly 99 times and still becomes seriously injured by doing it incorrectly one more time. I'm not trying to make an argument that you shouldn't exercise but it's definitely not "simple."

It is not disingenuous. Many crossfit exercises are complex as you correctly observe and require a good bit of practice before you can do them w/ any substantial weight.

A layman should not do them w/out instruction and a good coach will not let laymen do regular workouts until they have mastered the basics.

A good coach also observes a new student's abilities and advises them how to scale the movement properly as they progress. A bad coach does not.

for the same reasons, you should never attempt Olympic weightlifting movements w/out a coach, i.e. snatch and clean+jerk. In fact, I feel pretty strongly you should not learn how to squat or deadlift w/out a coach or personal trainer.

Well, considering you could get certified as a CF instructor in a weekend session, I am entirely unsurprised.

As someone working in academia, I'm fine with them attacking academia. There are a lot of objectively bad studies out there and sponsorships that shouldn't happen. Most professors don't care about open access or benefitting humanity, just playing the tenure politics game. There's some room for criticism between being head-in-the-sand anti-vax and blindly worshipping the journal-industrial complex. Academia needs to be taken down a few notches.

The fundamentals of Crossfit are entirely sound. A warmup followed by some subset of bodyweight exercises, calisthenics, rowing, running, climbing, and (olympic) weightlifting is a completely reasonable fitness regimen. Being sensible is a matter of leveling the workout to your own particular circumstances: age and overall fitness being the two biggest factors.

But yeah I've also seen the videos on youtube of people doing heavy barbell back squats on a bosu ball and similar, to use the technical term, stupid shit that will get you hurt.

Mark Rippetoe has one of the better criticisms of CrossFit: it's just an exercise program, not a training program. Proof is that the athletes that compete in and win the Crossfit games don't actually do Crossfit to prepare, they have specific training regimens for those games.
