Hi Peter Ralston,
I'm wondering how intrinsic strength applies in a groundwork context. Is it still possible to apply principles such as grounding when you're off your feet? My experience of ground fighting is that it utilizes a great deal of muscular effort, but I can't yet see how it could be otherwise. What are the options for applying intrinsic strength?
It is harder to use intrinsic strength when grappling on the ground. It isn't harder to use grounding though, since you can't get much more grounded than lying down!
First you need to learn the use of intrinsic strength before trying to use it in a more difficult situation. Usingintrinsic strength requires movement, alignment, and compression. While grappling, movement is reduced because of the nature of the art, but there is still movement. The more you can use the ground for compression the better. In grappling, positioning is very important since you have so little mobility, also leverage is essential. And yes, more strength is generally needed because of the situation, but still less strength than you might think, and much can be done in the area of yielding, maintaining the advantage, efficient use of weight and positioning, etc. All of the principles still apply, they simply must be translated into lying on the ground.
