Do this drill for the static push up starting point, standing and off the wall or ground and note how your body creates different points of support in these different tension and alignment conditions when you refer to support points and Mrs gravity 🙂
Take a knife that is not too sharp and a partner. Have the partner press the tip or line of the blade to your body including the head and work on pushing it away from your body with tension and movement using just the point you are touched with. This is of course not how you will do it to survive but a drill to feel the outcome and sensory input from fright and tension. Begin using the full power and tension in the body and once you and your partner (or you can do this solo by pressing the knife to you or fixing the knife in a jam and using that) have a go at this lower the tension to half and than to no tension. You need to recognize the tension before you can control it.
