I discussed with an expert in kinesiology and he agreed that Kurz slightly over-critisized static strething. Short streches are not dangerous, for examples.
Personally, I do them both and not necessarily exactly how Kurz advocates. The difference is clear for me when compared to mere static stretching.
As for the usefulness of static stretching, Kurz never said they are not needed. His net site is made in commercial fashion to promote dynamic stretching FOR people that do ONLY static streches and dont't get the results that they could and even injure themselves.
I believe in Kurz's stuff and I sincerely recommend trying them for anyone. There is nothing to lose.
