An interesting article on CrossFit
The attitude the author uses in addressing CrossFit is pretty critical and shows a lack of familiarity with CrossFit. There is, however, value to this article in that it brings to light the potential danger of rhabdomyolysis. This is why we approach workouts in a scaled manner at first, especially for those with athletic backgrounds able to push themselves too hard.
Another little interesting tidbit, CrossFit started in 1995, and at the time of this article had 50 gyms. As of now, there are around 1500 affiliates around the world!
