text: They are not original, and he claims as much.  But he does market them well enough.\n\nSome are okay, some are crap in a cheezy package.  Basically they are not much more than body weight exercises.  He "preaches" against weights...so you have to draw your own conclusion as to if he is right.   \n\nI have tried them, they are okay to start a foundation, but any good fighter will tell you it is not nearly enough...he's catering to the lazy!!!!
