Just went to my first Brazilian Jiu Jitsu lesson and these are the things I learned... 1.) Watching all the MMA in the world didn't help me all that much when it came to properly passing guard and turning into an arm bar. How the hell they make it look so smooth is beyond me. I move like a goddamn robot, forget to squeeze, forget to apply pressure, etc. 2.) Almost everything I thought I knew about BJJ from watching MMA was wrong. It's so easy to criticize when sitting on a sofa, but now knowing that I was only able to perform a keylock when my partner was lying there about to fall asleep, I'll never say, "He totally should've submitted him," or any inane, ignorant comment ever again. It's a lot harder than it looks. 3.) Having a full grown man sitting on your chest makes it very, very hard to breathe. Contrary to popular belief, I don't normally have fully grown men sitting on my chest. 4.) It was a great work out and I loved it. Also I am terribly out of shape. Hopefully that will change. Random thoughts from a complete novice who just finished their first lesson.
