Not sure how reliable this source is but he basically says P90X is not good for you:
Dear Dream: What is P90X and Does P90X Really Work?*|*The Dream Lounge
hmmmm, nice to know that someone "Dream" who has never used the program is saying it doesn't work.
From the thousands that have used it and have seen results I wonder what the explanation is. For me, his argument is very, very weak, he has questionable facts, and doesn't supply a fact based alternative.....he's just a wind bag with an opinion. If you go back and read Dream's blog for recommendations on reading and diet he actually has a book by Mark Sisson that he states is his number one pick for best reads. Go figure, Mark Sisson was one of the main contributors to P90x fitness and nutrition plan. Dream states "I can only fathom the stupidity of the
nutrition plan". I wonder if that would have changed his mind on P90x.
I'm not saying P90X is "the solution" but for me personally, it has worked. Not only that, it was at a reasonable cost and I did it at home safely. The program packaged a good workout (12 to be exact), it comes with a good nutritional program, and if you do the work you will see improvements. Are there better programs out there......probably but I haven't found one that gives me anything better than P90x. I'm willing to try if there is one.
