From the medical point of view what author says is true. Actually, it's not something new, there are many complaints about crossfit from knowledgeable people. Especially often I see powerlifters ranting about crossfit being harmful. But here's the problem. As you know HN isn't sports resource, yet article about CF is on top. Why? …You see what I mean? It's extremely popular amongst people that don't want to be powerlifters or swimmers or sprinters, that don't really care about competing at all, they just want to have some exercising program to follow and stay fit. Which is totally fair. For which crossfit is better than nothing (at least until you injure your ankle while doing box-jumps). And I completely understand those who doesn't follow advices like "don't do crossfit, do powerlifting" as powerlifting competitions cannot be the goal for them. What I'm saying is when there is counter-advice there should be advice as well. Now, Erin isn't a powerlifter and sure she provides something like "fitness training plan", but while the idea of crossfit training is clear (maximizing intensity whatever exercises you do) neither she nor others provide enough material for self-education to be able to do some "not-harmful crossfit". And people essentially want "not-harmful crossfit", not training for judo or sprinting or powerlifting… unless they do judo or sprinting or powerlifting of course. So, tl;dr: crossfit is harmful — nothing new here. "Train like an athlete, but train safely." — not informative/constructive enough.
