That sounds a bit gay and was never part of the art at my dojo.I did judo for a bit...when i briefly considered doing some mma (@Haggis. ) biggest thing was having to "let" guys through you. Some guys just cant and try to fight it.
Bjj from the 3 classes i had of that seems to be more focused on starting from guard shit.
Its definitely a useful combat sport...but...some guys who do it... In my opinion are sometimes not really "fighters". You can definitely get injured...but the better the instructor the less chance of that (from what ive seen...but im no fucking expert)
I was a blue on the way to getting my purple when I stopped because of my back. There's dudes who had just started when I got my blue belt that are purples and browns now.I personally found Jiu Jitsu much harder than boxing. Especially at the start where pretty much everybody is kicking your ass...and you will be on the losing end A LOT in the beginning. I was a blue, close to getting my purple when I stopped because I hurt my hip. It's better now, but just been too lazy to go back.
Although I must say, you can go much harder in BJJ without really hurting the other guy than you can in boxing.
