I bought the YRG Fat Burner Plus (the hardest one, 60 minutes) after seeing it posted here. After I got it, I posted about my thoughts on warriortalk, and a bunch of the guys over there have bought the YRG DVD's and are really liking them. I've spoken with DDP by phone, and he is a great guy. I am a big believer in YRG after doing it, and have just ordered the heart monitor and 20 and 40 minute DVD's. It is a great adjunct to your normal workouts, and as DDP says, "to turn back the hands of time". I believe it can do that, and flexibility training is one of the best things we can do as we age (I'm 47). I know that Grimel, who posts here, has been doing it as well and really likes it.
YRG is not your mother's ohm muttering, birkenstock wearing, earth biscuit Yoga. It is all about strength and flexibility, and it gives you a good cardio workout in the process.
Arthur Boorman, the guy in the video, is a true inspiration. What he accomplished in a years time is nothing short of amazing, and he is now one of the best ambassadors for the YRG program.
