Can't divulge the secrets they gave us man, sorry. Pony-up next time and get there!
Just kidding (kind of). Honestly though, it would be very hard to pass on form/technique tips as that part was very hands on. One of the biggest lessons I took away (aside from the technique tips) is that these guys don't have any wild training secrets or muscle building secrets. They're just really hard-working guys that put their time in under the bar just like any of the rest of us can do. The biggest difference is that they don't make excuses like everyone else, they stay consistent, etc. Eat fairly well, rest, train smart- that's what these guys are doing, for real.
Also, I guess form/technique wise, if you're not feeling all sorts of uncomfortable and jacked up (in a bad way) doing bench and squats, you're probably not setting up correctly!
If you have any specific questions I could try and answer them, but it will probably be stuff you've heard before because like I said these guys don't have super secret training info and stuff like that. The value in the seminar really was being there for the hands-on coaching.
