, tension and body geometry: A huge part of your or failure in grappling will come down to your ability to control your opponent's movements by FITTING THE GEOMETRY OF YOUR BODY INTO THE GEOMETRY OF HIS in ways that MAXIMIZE CONTACT AND and thus inhibit movement through CONNECTION RATHER THAN MUSCULAR . The you must gain is that THE ONLY WAY TO MOLD YOUR BODY INTO THE GEOMETRY OF YOUR OPPONENT'S BODY IS TO RELAX AND YOUR OWN BODY. However, the only way to KEEP yourself locked into that position is to tighten yourself. Thus you must play the same delicate balancing between relaxation and tension that a python does when it wraps around its prey. YOU MUST BE SOFT WHEN MOVING TO FIT INTO YOUR OPPONENT, THEN TIGHTEN TO SOLIDIFY YOUR POSITION ONCE THERE. Often you will have to work in cycles of tension and relaxation to get the job done. Here, Gordon Ryan shows superb conformity to the shape of his opponent's body – made possible by relaxation- but also tightness to hold himself once there against a very skilled opponent like as he patiently works towards a match winning .
