I love it when I get asked a question that is outside the normal BJJ sport frame of mind; at the end of class one of my female students that is new to BJJ said that one of her biggest fears is someone sitting on her chest in a very high mount and their shins/knees over their biceps trapping their arms. My first thought; I would never hold mount like that (automatic BJJ sport response, Duh), it took me a moment to catch up and get out of the sport BJJ world, she wasn’t saying what is a mount escape, she was saying “This terrifies me, what can I do?”.
Well After I work out what i thought was a viable concept of an established mount escape, and testing it out with her, she asked if it would work on someone bigger than me. I said I don’t know, lets find out. I called for my assistant coach Joe to come over, I weigh 180ish he’s about 235. I asked him to get into the position in question and his reply; ” I wouldn’t hold mount like that” ( so it’s not just me). We tried a couple other variations for that situation but it seemed to work. Before writing this I wanted to test the concept one more time with Coach Tom, he’s about 265 , it took a little more effort a but worked as well and decided to put it out there and put it down on video.
Keep in mind; I’m addressing this as a “concept”, this in one instance in what could be an assault or rape situation. This is not meant as a end all solution but only to show that you have options and hopefully that it sparks an interest in learning some options for escaping from the ground. If it starts you on a Jiu-Jitsu Journey all the more awesome, but find a good gym with a good coach that will answer your questions.
