Why did you have to take BJJ Classes?
Oh, everyone always complaines when I talk about this stuff on here that I've never taken BJJ for weeks, months, or years, whatever.
We went to a couple of seminars, and have trained with BJJ students of 8 onths to 10 years in our sparring classes back when when had a building for the school.
It just isn't an art I want to devote time to learning from what I've been exposed to. It'll just mess up my WC/WT, get in the way of working on striking and keeping my space from attacker when they are in grappling range. I don't want to play their game, I want to play my game, WC/WT.
