Lets do a little myth busting.
First, yes, it is true that Crossfit exercise routines will help you lose weight.
But it is also true that Crossfit is dangerous, pushes people to extremes and even causing exercise addiction - and the resulting Crossfit devotees (or should we say addicts) get really into all the activities done at crossfit gyms - but the repetitive strain and the injuries pile up, which can lead to extreme injuries.
In fact to outline just how dangerous Crossfit is why not Google the words 'crossfit injuries' and read some of the 1.17 million webpages on the topic.
What is also funny is how many Crossfit enthusiasts (addicts) tell fellow enthusiasts to "suck it up", "no pain no gain", "don't be a wussy", etc whenever the topic of injuries come up.
And we're not talking mild injuries. We're talking about people who injure themselves so much they can't even walk any more.
That puts it on the same level as people who are so anorexic they cannot walk any more, or people so obese they cannot walk any more... in this case it is people who exercised so much they injured themselves and now they cannot walk any more.
Cannot walk, are in severe debilitating pain, and in some cases will be like this the rest of their lives.
There are Iraq War Veterans out there missing limbs who are in better physical condition than some of the Crossfit devotees who injured themselves because they didn't know when was a good time to rest and recuperate.
So let me break this down for you.
When you exercise, weightlifting for example, you need about 24 to 48 hours (sometimes more depending on your age and how much weightlifting you do) in order to repair all the muscle tissue you ripped during your weightlifting session. With weightlifting you are often only challenging a few parts of your body at a time, which means your body only needs to repair muscle tissue in those areas after the exercise is over.
The purpose of Crossfit however is to rip muscles in almost every muscle in your body by pushing your limits in many different ways. Afterwards your body heals up and you end up being stronger all over (not just in specific muscle groups)... but because Crossfit is addictive you end up with people who are doing it 5 to 7+ times per week, leaving your body almost no time to repair itself.
Lack of repair time leads to repetitive strain injuries - and repetitive strain rip tendons.
Do you know how to fit a tendon?
Lots of surgery. It is painful and truth be told whatever body part you ripped the tendon in may never be the same again. It is a bit like someone who has a heart attack. Once you have your first heart attack it is pretty much all down hill from there.
Below is a photo of a ripped tendon in someone's arm being repaired via surgery. If he is lucky he still has full use of his arm, but the chances are more likely his arm will be in pain and have restricted motion for the rest of his life.
And this is just one of the many injuries people can develop from Crossfit.
As a personal trainer I actively discourage all of my clients from activities that could result in any kind of sports injuries. Yes, I know you want to lose weight and gain muscle - but sports injuries are not worth the risks associated with 'extreme fitness' activities like Crossfit.
In other news, Happy Halloween! I hope the above photo scared you away from Crossfit.
Oh and mountain climbing. That is pretty dangerous too. Trust me, I nearly died twice in South Korea while climbing mountains there. The view up there was nice, but in retrospect I should have taken the safer route to the top.
