You're doing this on purpose aren't you?
I love a lot of his ideas such as exploiting your strengths (to a point). I also believe that the introduction parts of the book (all the stuff before actual training guidelines) is the most useful part of it. Very good for getting people in the right mindset. I wish I had read some of that way back when.
I think he's a good guy who really wants to help people. And obviously training by his recommendations is better than sitting on the couch or playing video games all day. But I think it is pretty much TOO conservative. If the only other thing people had to go by was Arnold's stuff then I would be saying this is the shit. But times have changed and we know some more concrete things about frequency, volume, recovery and all that. So while I think many people could benefit from his ideas I do not think it is OPTIMAL for the majority.
In general I think it just feeds peoples tendency to fall back on that tired old "hardgainer" excuse and cry about overtraining.
L-Fly's, btw, as described, are simply external and internal rotations done with a dumbell. I can see a lot of silly stuff like doing those horizontal shrugs on a program with no rows.
