i have benefited immensely from Billy Blanks Taebo CD's. i started using his workout from second week in May, 2010. since then i have experienced drastic weight loss. i work out one hour every morning before going to work. i varied the CD's to achieve maximum benefit. so far i have six different Billy Blanks CD's including this one. i used it every morning from Monday to Friday and go on a two hour road walk on Saturdays. i recommend Billy Blanks workout for anybody who wishes to lose weight and keep it off for good.
