Josh came over again last weekend for more BJJ drilling. We both bought BJ Penn's new book about the closed guard, and since we worked on some posture issues last week, we decided to drill some of BJ's techniques for breaking top guy's posture when he's in your closed guard. We were pretty amazed at some of the results we were getting.
We also tried out Penn's armbar drill and triangle drill. These were a little tougher for me, because I have no experience with this type of motion yet. His armbar drill was especially confusing to me. I'm not (yet) sure what BJ's doing with which legs in order to move like he does. I'll get it though.
