Tom sent me a link from the Air Force Times that points to some injuries and rhabdomyolsis experienced by Air Force personnel from the kind of excess training that not only CrossFit, but P90X and other "high intensity" training may lead to.
There is no danger of RHABDO in the very brief and intermittent form of HIT that Evolutionary Fitness teaches. Variety and randomization, as well as not setting performance goals, are protective and are principles of EF. Power Law training is so natural it is almost impossible to get injured. You NEVER go to failure, nor do you do multiple sets or too many exercises in a single session. You work out in a relaxed, non-competitive way with very brief intervals of high intensity. Just the ticket and completely consistent with the way wild predators work and children (natural little predators) play (rehearse skills of the predator).
My own experience is not proof that it cannot happen, because people do the strangest things (myself included), but I have been working out for 60 years, the last 25+ years based on EF principles. No RHABDO here and no injuries either, though I did have a couple before getting it right when I was doing more conventional training. Once I fully switched to EF, and that is at least 25 years ago, I have been completely injury-free. I take that back, I did injure my IT band doing stretches when I used a trainer for a brief while. It is hard for a trainer to know your limits and you try to show you can do what they ask. This is a potentially bad situation that an experienced EF trainer would be able to avoid.
