In beginning class last night we went over the basic Guard Escape that is shown in Brazilian Jiu-Jitsu: Theory and Technique (Brazilian Jiu-Jitsu series) on page 62. I reference the book because it is a good starting off source for the new white belt that wants to get a handle on all the new techniques they are learning.
We then worked on some counters for that escape as shown in the other videos I have posted. The second counter was new to me and it sparked some thought. There are underlying physics to BJJ that seem to be at the edge of my conscience. I struggle to define them and put them into a concept. I think the guard escape counter 2 is a example of pry or multiplied force. Mark also showed us how if some one straight arms your hip to keep you from coming around how that is easily counter buy tripod-ing up. This changes the force of your body to down on the arm. Chris then pointed out that if you stick your knee in you easily push the arm away. I think this is also a physics principle. Some thing of the effect that a force can only be applied in one direction. What ever the case, if you are pushing the hip and another force, your opponents knee, pushes perpendicular to your arm the direction of your force is moved out of the line it is in. Ok, this may be way to deep for a text discussion, especially for us visual learners. That is why I am having a hard time making it a solid thought in my head. Maybe it is time to brush up on my physics. Its been 16 years since my college 101 class.
Jiu-Jitsu is Life and Life is Jiu-Jitsu.
