Not a knock on Hany; but wasn't majority of what this guy knows taught to him (and George Farah) by Chad Nichols?
King Kamali made a real good point on the recent RX interview: It's very easy to take someone with elite genetics and dial them in to look freaky. Turn chicken shit into chicken dinner, and then we'll talk.
One of the reason why DC training was so popular, it took the average guy and brought him up to his genetic limitations of muscle mass in the fastest way possible. At least chicken shit was a bigger chicken shit this way.
