This is what I have... You'll get 3 BP videos, 3 squatting videos, and 1 DLing video.
In the BP videos you'll see taped workouts of westside speed days, and max days -- and then louie goes over how to do a lot of exercises you may not know about. Also, "Don't do that Marvin."
In the squat videos, you'll see box squatting on the first tape I think, and then ME work on the second video. You'll see several different possibilites for ME exercises performed, and you'll also see all the assistance work. Throughout all the squat videos, there are good tips on form, lots of helpful little pointers.
The DLing video isn't very good IMO. It starts with a half hour speech by Louie about good DLers from his gym, and then goes on to show you a bunch of ME Squat exercises that will help your DL that you already saw on the squat tapes.
These were pretty valuable to me as I basically have been learning WSB on my own and needed to see everything with proper form. There are lots of available training websites with videos online now that weren't there a couple years ago -- so you could find the proper form for a lot of the exercises. It is really motivational however, to see it from Louie himself.
As for the seminar package -- all I've heard is good things.... hopefully somebody can outline it for you so you can compare it to this.
