I'm 38 years old, so I'm basically a fossil. Tried to get my daughter into it, she didn't really care for it too much. It is my old friend's academy, so I gave it a try. First class kicked my ass bad. I was dying after the warm-up. Learned guillotine escapes. Legs and neck hurt all week, loved it though. Next week learned bear hug escapes and side control escapes. Wasn't nearly as sore this time. Learned a cool Ronda Rousey judo throw. Anyway, this stuff is pretty expensive. Not sure how long I'll be able to justify it to my wife, but I do like it. How can I get the most out of it, and what should I know?
