I'm 40 and way out of shape. I rolled with a 180lb 17 year old that put me in some crazy mess...that he probably really didn't know what to do. We were both gassed and he was on my back...literally sitting on my back...he grabbed my head like in a WWE back breaker and I tapped because I was getting dizzy.
talk about feeling like a kentucky fried bitch....
I have tapped to all ankle and leg locks, mainly because as a white doing this less than a month I have no game there. I don't know any locks or escapes...so if I'm rolling with a blue or a purple, at our school they are told no leg locks. One guy on his trial class who had been doing BJJ for for years almost was ready to hand me my own foot..the instructor dove in and said "no leg locks!" but I had already tapped...
