i'm sorry but scott herman doesn't really know what he's doing. watch a lot of his videos and you'll see him get flamed for incorrect form etc. just because he can move a lot of weight doesn't mean he knows what he's doing.
check out kevin levrone, a legendary body builder who is now off roids and started a website offering free training videos and nutrition tips:
www.levrone.com. i haven't been keeping up with a lot of his stuff recently, but definitely check out his old "transformation" videos (you can find them on his site or his youtube channel levrone2000), where he goes into detail about form, sets, reps, supersets/dropsets, etc.
i'm also a fan of victor costa
good luck!
