Oh! I see what you're getting at. But you know moves themselves are not bad. I don't know anything about crossfit but I saw guys rolling the tyre or doing stuff with thick ropes or climbing, excersising with kettleballs and it looked kind of hmmm … My drummer always says to me. If something is stupid but it works - it's not stupid xD
About the preaching thing. You're right but it happens with everything right now. If something is trendy and there is a fashion for it people tend to do it and pretend they are now specialists at that and it's the best in world and how can you be so fucking blind to not see it. It was with hipsters, with natural products, gluten-free guys, crossfit and my beloved VEGANISM. I'm sorry I just hate vegans. It's stereotype I know but I'm on them like you're on crossfit. They will tell you that it's the best in the world and why won't you just fucking stupid moron try and do it for the planet and your body and everybody can lift weight wtf are you doing it's about balance and inner stabilization FUCK OFF. But that's just ... hm I would say unlucky 30 % of those people. There are people who actually do it, dedicate to it and don't shout it to the whole world and don't show off.
Of course calisthenics is also great and works nice on your mobility. If I wasn't so lazy and had cash I would do it too. For now I will just stick to usual exercises. +gym routine should be changed from time to time to actually stimulate muscles and don't block the grow. Here Calisthenics is pretty common. Probably thanks to my buddy. I don't know him this much but the guy went to the school with me. He started few calisthenics school in our city and was representing our country in world championships.
Hmm CrossFit is a trademark I think. Like Coca-Cola. There is one Coca-Cola but you can have pepsi or you can make products that simulate it. As far as I know a crossfit would refer to a style of exercises though I'm not sure. It contains lifting weights too but it's also training with every other equipement. It has certain targets which I believe few of them are mobility, flexibility, motricity, efficiency and blah, blah, blah. It came from a policeman and marines training so it's like a routine that was made for them to train (I believe everyday) for not a long time (as lifting weights takes but with less visits). I think it also doesn't have any breaks between sets or repetitions.
