I really need to start coming to this board more often. I used to be pretty into the whole Crossfit idea, but it's funny how the more you learn the less it makes sense. Especially now days. Trying to figure out what exactly CF is and what does and does not constitute "doing CF" is like trying to hold smoke in your hands.
I also find it interesting how much of a hold it has on people. On the boards there are MANY examples of members (even affiliates) who will readily say that the things GG says are stupid and exaggerated. As well, everyone sees through whole "open source" bullshit these days as it is the most heavily censored website I've ever been to. And yet it remains. Just interesting.
I did want to ask a question about some of the stuff that has been brought up in this thread though. It has been brought up that box jumps cause a lot of achilles problems because of the rebound at the bottom. Does that make jumping rope dangerous? What about sprinting? They do similar types of things to the achilles don't they? Is it the height of the box and the number of repetitions that makes it worse? Also there were posts where tire flips and KB swings caused injuries. Why are these bad movements? Are they bad or did the person just happen to get hurt that day? What if you did KB swings to only eye level instead of overhead? Are they still bad?
Sorry for the barrage of questions. I'm not trying to defend box jumps or anything. I really just want to know for my own knowledge.
Finally, I noticed someone posted pictures of this earlier, but I'm surprised nobody put up the video:
Apparently irreparable shoulder damage is so functional and elite that it should be celebrated...
