I switched to BJJ been doing it for about a month and a half. I signed a year contract so I'm stuck with it. I enjoy it. But it is rougher than I thought. Quite a bit of excersize. Rolling can be fun, but it just sucks when you are so worn out from excersize you end up just letting the person submit you instead of fighting back near the end of the class. But I need the excersize so its all good.
