I was thinking to order secerts of stretching, stretching scientificlyby Tom Kurz, and gold medal mental workout, and power high kicks with no warmup off of the same website, but but when I called to do so the lady on thew phone was very rude, and I can only imagine how their service after the sale would be. Does anyone have any of these books and can anyone give me a review , cause if they are good books that work I will order anyway. thanks.
