I would say that you can't really throw someone if you're unstable (well, you can, but not very well) - so by "unthrowable" I'm talking about a kind of stability training (in a sense).
Thanks, that does make sense. Although to me it doesn't sound like being 'unthrowable' per se, so much as being un-unbalanceable. Which I can certainly see the utility of. (Though I still imagine it's not literally infinite. I mean if you get hit by a car you'll fall down
No matter how stable I am if someone strong enough bends their knees, wraps their arms around me, and unbends their knees, they can lift me. (and therefore throw me if they want)
