""I have never agreed with the “X Factor” theory because it equates muscle tissue with the elastic properties of a rubber band.""
Nonsense.
I think people don't want to understand.
If I "load" my thumb against my forefinger so as to "flick" someone, the issue is not the "elastic" properties of the muscle tissue involved, it is the 'load' of one part of the body against another. And there is definitely an advantage gained.
Similarly, when the upper body goes rearward as the hips open the "elastic" properties of muscle tissue involved isn't the issue. You have simply turned one part of the body in a direction "against" the other.
