Most successful trainers these days are going to market toward "skinny hardgainers" rather than bodybuilders. Its just smart business. You figure, most bodybuilders aren't going to go buy a book like that or a program from a similar site. They'll probably follow a program like DC or something that some other successful bb'er has used.
Also, for every bodybuilder out there, there is probably 5-10 "skinny hardgainers" that are willing to shell out the money to "get big". And you cant blame the guy for bashing bodybuilding programs, because in general the FLEX magazine, and Muscle & Fitness programs of the past and present are pretty much crap.
Sure this is an arguable point, but these programs will more often than not be useless for the beginners that are actually going to try them. You cant simply pick up the routine a 300lb bb'er has been using for the past 6-weeks and expect to get the same results as him.
Also, JF deals with athletes, and many average joes that want to be like athletes. These individuals SHOULD train like an athlete, not like a bb'er. And it seems like he's adopted a pretty good philosophy with using mainly compound free-weight movements, and throwing in a few isolation movements here and there.
The thing I find funny, is his marketing. Im sure he did his research and used a successful marketing template, but it just completely turns me off. Here is an example:
"I Accidentally Stumbled Upon the Hidden Research that
Finally Revealed the Secrets of Unstoppable Muscle Growth
What I discovered that day in the university library utterly blew me away and went against everything I had ever learned about building muscle and strength.
Beyond intrigued, I immediately applied these findings to my own workouts. After many years of frustration and disappointment, I finally began to pack on muscle so fast it was scary.
Within the first month I went from 155 to 177 pounds! I gained more muscle in four weeks than I had in the previous four years! Everyone thought I was on steroids, even though I could barely afford my gym membership, let alone thousands of dollars worth of dangerous drugs."
So he discovered "hiddent research" that stated you must eat a lot to gain weight? And this went against everything he had learned about bodybuilding? Because I dont know about you, but I know for a fact that his training had VERY LITTLE effect on this 22lb weight gain in 4 weeks. Unless his training was picking up cattle and running with them, and then eating them.
I dunno this just throws up some red flags to me. It reminds me of Jimmy Smith's product that came out a while back. He hyped it up so much, making all these claims, and really it seemed as if he spent about 2 hours on the actual information and the rest of his time on marketing it.
But I have seen some example workouts from JF's programs and they look pretty solid. As I mentioned above, it doesn't really take much for a program to be good. As long as it has you working your entire body, lifting heavy weights and eating right, then it CAN work.
But I think these pre-made programs are for the most part a waste of money. This site here has enough info for you to design your own program for free, unless you are a complete idiot.
A beginner should follow a pre-made program for one or two cycles, but after that they should be able to create their own.
