TL;DR: I got rhabdo from crossfit last year. My CPK was 100,000 and I spent 5 days in the hospital. I wasn't overweight but I wasn't fit when I got it, and I got it during the first day of a beginner course.

Ask me anything.

==============================

I did crossfit for a couple of months in 2010 and loved it, but I had to stop since I moved to a new apartment and the gym times wouldn't work with the longer commute. I always wanted to go back, so in June 2012 I started up again, taking the two-week beginner course (I wasn't in the best shape and I wanted to ease into it).

During the first day back, we went through a lot of basic movements and listened to the instructor talk about what crossfit was like. In the hour-long class, we spent the last ten minutes talking about rhabdomyolysis; what it is, the symptoms, the danger, common ways to get it, etc.

The workout of the day was tabata squats (20 seconds of as many BW reps, then 10 seconds of rest, repeat 8 times for a total of 4 minutes and 2:40 of exercising), tabata pushups, and tabata situps.

The squats were the one that got me.

The next morning, I couldn't walk, but that was expected since it was my first day back. I pushed myself quite hard (knowing what crossfit was like), but I wasn't competing with the people in my class, I was competing with myself. I took it easy and rested.

The day after that, I couldn't really bend my legs because of the extreme soreness, and walking down the stairs was neigh impossible. It took a while, but I took the subway to the office where there's a gym with a stationary bike, as slow biking was the only thing that would ease the soreness in my quads.

After 6 hours at work, periodically biking and reading online, I noticed my urine was coca-cola colored, and that it was the telltale sign of rhabdo. I knew that because the crossfit instructor drilled it into my head two days earlier.

I looked online for a hospital that my insurance covered, took a cab, checked myself in saying I had rhabdo, and I began a 5-day stay where I received lots of saline solution (1000ml 6x a day, IIRC) to help flush the myoglobin out of my body. Luckily for me, the hospital saw a lot of cases of rhabdo from not crossfit members, but prisoners. They have little else to do than workout extremely hard, and the hospital saw dozens of prisoners a year.

My creatine kinase was almost 100,000 (excess myoglobin is the problem, but high creatine kinase is a proxy for high myoglobin, and CPK levels are commonly checked). TFA is right in that the normal is < 100. IIRC, the doctors estimated I dissolved 5 lbs of muscle tissue into my bloodstream to get a CPK that high. I was bored in the hospital so I charted my CPK to determine when they'd release me: http://imgur.com/18HYKNr

==============================

Many tests afterwards showed my kidneys are fine, and I haven't noticed (or read about) what the TFA describes as "flabbiness" or some sort of water retention in my legs. I also haven't noticed that my legs are weak; on the contrary, after lots of biking over bridges my legs are stronger than my squat days (at least when it comes to endurance, not power).

TFA is being a bit sensationalist and anecdotal about rhabdo being crossfit's "dirty little secret." To add another anecdote into the fire, everyone I know that does crossfit knows what rhabdo is, and rhabdo is mentioned in beginner classes multiple times; not only what it is, but the symptoms, what to do when you get it, and how, if left untreated, myoglobinuria can lead to acute renal failure and death.

I haven't been to crossfit in over a year, but TBH I'm itching to go back. I'm the kind of personality that will really push myself hard – probably harder than most – but now I know a little better and will hold back a tiny bit, especially when doing high reps of low weight.

==============================

Update: My first crossfit experience was at Crossfit Virtuosity in Brooklyn, NY and I got rhabdo at The Black Box in NYC.

Also, my memory isn't so great as I thought. I took the class on a Friday and, that same night, moved into a new apartment. The combination of crossfit and carrying lots of boxes/furniture on the same day was probably the cause.

That's scary. Thanks for sharing.

I'm an amateur bodybuilder and I workout alone. Over the years I have contemplated joining Crossfit (mostly for the comradery aspect), but the insane level of cult mentality has made me shy away from it every time. Articles like this just drive home the point.

My friend Jane, who is a physical therapist, specializes in exercise injuries. She once confided in me that local Crossfitters form by far the largest percentage of her repeat customer-base. She said she finds the level of irrationality unbelievable, in that the same people will come to her in a lot of pain and brag about their injury on the one hand, and beg her to fix them up quickly so they can go back to Crossfit ASAP. Then they will come back in a few months with a different injury but the exact same mindset.

Re:CrossFit's Dirty Little Secret by kyllo on Saturday September 21, 2013 @10:14PM (#6425511)
Yeah I know a few people who have tried Crossfit and the had to quit because they got hurt within the first month.

SLAP tears from excessive kipping pull-ups is another common crossfitter injury.

I think they do a lot of exercises that are very dangerous to the shoulder / rotator cuff in general. Back injuries are pretty common too, since proper spinal posture is one of the first things to go out the window when you get fatigued.

Re:CrossFit's Dirty Little Secret by mathattack on Sunday September 22, 2013 @11:22AM (#6426868)
I hear horror stories of injuries too. In the end it's self defeating if you are injured all the time or so exhausted that the overtraining hurts the rest of your life.
Re:CrossFit's Dirty Little Secret by kyllo on Sunday September 22, 2013 @10:38PM (#6428927)
Yeah. Actual sports teams never have their athletes do Crossfit because the number one commandment for strength & conditioning coaches is: Don't injure the players!
Re:CrossFit's Dirty Little Secret by scott_s on Saturday September 21, 2013 @07:35PM (#6425062)
I don't do Crossfit, but I think it's a good system in general. I do powerlifting style strength training and Brazilian jiu-jitsu. The attitude you're talking about - patch me up so I can get back to training, until my next injury - is common to all sports and physical activities.

Now, it's possible injuries are more common in Crossfit than in other sports, but that's a question for the data.

Re:CrossFit's Dirty Little Secret by mason55 on Saturday September 21, 2013 @08:18PM (#6425196)
Wanting to be fixed correctly so you can be healthy and return to your activity is just a sign that you love what you're doing and have goals. Being proud of being hurt is totally unhealthy.

Ever seen Jaws? This is a famous scene: http://youtu.be/dLjNzwEULG8 Every sport culture I've been exposed to has an element of this.
Re:CrossFit's Dirty Little Secret by mathattack on Sunday September 22, 2013 @11:23AM (#6426872)
Brazilian Jiu Jitsu also has a combat aspect. Injuries are expected. Strange to expect so many injuries from a pure fitness activity.

That's a good reason to shun a particular location or instructor, but I and a lot of other people have had completely opposite experiences. If the workouts interest you, I encourage you to give it a try and see what the instructors are like. Maybe ask Jane where her patients work out and go someplace else.

I think calling crossfit a cult is a bit extreme, but isn't this what people in a cult would say anyway? Normal people who join cults don't think they are crazy or it's a bad environment or that they are being unfairly pressured into doing things (generally).

I'm sure you could post a critique of Scientology and have a member come along and say "we'll I've had a very different experience with Scientology" and they'd be 100% correct (they would have indeed had a different experience). I have no doubt people have positive experiences from crossfit, else it wouldn't be so popular, but that doesn't change the issue of whether that environment promotes risky or harmful behavior.

>>That's a good reason to shun a particular location or instructor, but I and a lot of other people have had completely opposite experiences.

Before I posted that, I knew that a Crossfitter would respond and defend Crossfit. That is the level of cult-like irrationality I am talking about: looking at statistics (such as the ones about much higher incidence of Rhambo in Crossfitters) and responding with anecdotal evidence like, "well, my experiences are very different!"

Re:CrossFit's Dirty Little Secret by dkarl on Saturday September 21, 2013 @06:23PM (#6424851)
After you went out of your way to thank someone for an anecdote that confirmed your bias, you'll have to forgive me for believing that you're reacting to my point of view, not the nature of my evidence. All I said is that you should see for yourself and trust your own judgment. To quote myself, "they don't do much to actively ensure the quality of local affiliates.... I wouldn't encourage anyone to blindly trust whatever local Crossfit affiliate happens to pop up down the block."
Re:CrossFit's Dirty Little Secret by enraged_camel on Saturday September 21, 2013 @10:33PM (#6425562)
>>After you went out of your way to thank someone for an anecdote that confirmed your bias...

You sound hopelessly confused. We are not discussing anecdotes. We are discussing actual statistics provided in the original article that clearly showed Crossfit to have much higher rates of injuries and potentially-fatal medical conditions.

When you put the burden on new people to figure out whether their affiliates are high quality, you are blaming the victim. Most beginners are not capable of accurately assessing whether the types of workouts done in Crossfit and the manner in which they are done are healthy or not. What they do is read reviews of the gym on the Internet and see all the five-star raves, then visit the gym and see everyone cheering each other on and having a good time, and think, "hey this is cool, I want to be a part of it too!" Are they supposed to know about normally ultra-rare conditions like rhabdo? Or should Crossfit do its fucking job and keep its affiliates in check?

Re:CrossFit's Dirty Little Secret by spinlock on Sunday September 22, 2013 @01:59AM (#6425963)
I know the article's title calls rhabdo a secret but if you read the article - and the comment at the top of this thread - you'll notice that Glassman and every CrossFit coach I've ever met talks about it all the time. In fact, I bet you can't find one person who does CrossFit who doesn't know what it is.
Re:CrossFit's Dirty Little Secret by enraged_camel on Sunday September 22, 2013 @02:33AM (#6426013)
>>you'll notice that Glassman and every CrossFit coach I've ever met talks about it all the time.

Look dude, the problem is not that they don't talk about it. The problem is that they make people do complex exercises in a manner that significantly increases risk of rhabdo and a ton of other injuries despite knowing about those risks. This is irresponsible at best and grossly negligent at worst.

There is a way to lift weights in a safe and responsible manner. Crossfit not only refuses to teach its clients that, but also builds and encourages a culture where injuries become badges of honor. That is what makes it a cult.

Re:CrossFit's Dirty Little Secret by mudetroit on Sunday September 22, 2013 @01:24PM (#6427219)
FWIW,it can absolutely be that way, and I have visited at a few gyms that I would never go back to. I also know that at my gym, if a coach notices you breaking proper form at all they immediately work with you on it, or have you back down an bit be it in speed or weight.

I am in no way saying that the bad behaviors described above, and you can absolutely get a cult like mindset focused around entirely the wrong thing. I would also say that I think some of the nature of the workout strategies in general may attract these kind of behaviors.

Re:CrossFit's Dirty Little Secret by spinlock on Sunday September 22, 2013 @09:20PM (#6428768)
Sounds like a great startup to me. People who get it, love it. Everyone else is agressively defending the status quo. You sure do make a lot of enemies when you disrupt an industry.
Re:CrossFit's Dirty Little Secret by drumdance on Wednesday September 25, 2013 @02:29PM (#6446370)
One data point, but I did Crossfit for two years and don't recall this ever coming up. Fortunately I never got seriously injured, but I stopped because I came to dread the workouts. Now I do a less-intense-but-still intense cardio sculpt class and I actually look forward to every class.

> We are discussing actual statistics provided in the original article that clearly showed Crossfit to have much higher rates of injuries

This is equivalent to saying that surfers are more likely to get be the victims of shark attacks. No duh. It's a trivially obvious conclusion, but still really unlikely. CrossFit has done its job in educating people about the seriousness of rhabdo. There's absolutely no way they can ensure that none of their affiliates go off the deep end with craziness. That's a fundamental fact of scaling a business.

You're only looking at the negative side of this issue. But the reality is that from the high level of systems analysis, it's a tradeoff. For every person that has gotten rhabdo from CrossFit there are thousands of others that have had their lives significantly improved. In my case I got stronger and more fit. My body fat, cholesterol, and blood pressure decreased and I have actual data to prove it. I also noticed increased quickness, agility, and reaction time in everyday life.

> Most beginners are not capable of accurately assessing whether the types of workouts done in CrossFit and the manner in which they are done are healthy or not.

This is the case with a number of disciplines from fitness to martial arts to dance, so there's no substitute for educating yourself and making an informed assessment of the risks and rewards.

Re:CrossFit's Dirty Little Secret by fragsworth on Sunday September 22, 2013 @01:36AM (#6425931)
There is a very obvious cult-like mindset among a huge number of Crossfit members. You're being really dishonest by pretending it's not there, and it makes you seem like one of them.

I know several people who started doing Crossfit and they became fucking lunatics about it. It's got that bad smell of crazy on it, like Scientology and pyramid-scheme scam companies.

Re:CrossFit's Dirty Little Secret by mchughj on Saturday September 21, 2013 @07:32PM (#6425054)
I think that you should go back and read the prior response and then think a little bit about whether or not it represents a "cult-like irrationality".
Re:CrossFit's Dirty Little Secret by enraged_camel on Saturday September 21, 2013 @10:44PM (#6425586)
If you showed someone how fucked up Scientology is, and they came back with, "well, my experiences with it have been totally different - your local church must be bad. You should have done better research before joining it!" then yeah, that would be complete cult-like mentality.
Re:CrossFit's Dirty Little Secret by kareemm on Sunday September 22, 2013 @02:18PM (#6427391)
Given that there are high degrees of variation in quality across CrossFit affiliates, it's possible that customers of one box have better and safer experiences than customers at another.

If this is true -- and it is -- then "well, my experiences with it have been totally different" is also true, and has nothing to do with being cult-like.

Repeated injuries like that are a MASSIVE risk factor in developing osteoarthritis as one ages. OA can force you to be sedentary due to pain, and being sedentary as you age is a death sentence.
Re:CrossFit's Dirty Little Secret by sshillo on Saturday September 21, 2013 @08:40PM (#6425260)
I've been training at Crossfit Virtuousity for 5 months, 4 days a week. I think that they have an amazing program that reduces risk of injury as compared to many other non crossfit workouts I have done in the past.

First off they stress mobility, which many workout regimens don't do. I never really realized how important this was until I started crossfit. Most workouts consist of 15-20 minutes solely concentrating on mobility.

Second, no one has mentioned the concept of scaling, which is core to crossfit. Every workout has a scaling option so that you don't push yourself too hard. If you can't do a pullup you do it with a band, can't do that, do a box jump pullup, etc. Yet another way crossfit keeps one from getting injured.

Good point. I too remember the shock and amazement that washed over the entire training universe when Crossfit invented progressive resistance and skill progressions.

The only thing I can remember that was more impressive was that time Greg Glassman invented gravity. That was incredible.

Re:CrossFit's Dirty Little Secret by ryall on Sunday September 22, 2013 @03:43AM (#6426143)
That's an impressive level of sarcasm, but I don't think he's saying that scaling is exclusive to crossfit, just that it's actively encouraged.

No problem; I'm glad that people can get something out of my experience.

I originally wanted to write everything down and be a primary source of information on exertional rhabdo (there isn't a lot of useful information out there regarding hospital stay, CPK levels, etc.) but it got written down on a long-lost TODO somewhere and forgotten.

Re:CrossFit's Dirty Little Secret by osvaldof on Sunday September 22, 2013 @04:33AM (#6426240)
Wow this is a bit scary!

I started an high intensity program 2 weeks ago (p90x) and I had some pain after the first day for at least two days but I didn't pay attention to my urine. Should I go to my doctor? If I had rhabdomyolysis would I get any other symptoms after a week?

This is a normal practice in several European countries as well, so it really depends on in which "Europe" you live.
Re:CrossFit's Dirty Little Secret by kyllo on Sunday September 22, 2013 @10:39PM (#6428929)
That's horrifying. There's absolutely no excuse for pushing a recreational exerciser to the point of contracting rhabdo. Gross negligence on the instructor's part IMO.
Re:CrossFit's Dirty Little Secret by Whitespace on Monday September 23, 2013 @05:32PM (#6434302)
Where did you read that the instructor pushed me? I pushed myself that hard, plain and simple. And then afterwards I did even more lifting (moving apartments).

I overexerted myself, plain and simple.
