I have not done NROL so will probably read and do that one or the TT one that you all mentioned....
Here are some that I have done, and have loved. Or just look up these authors, they are all sort of tied in some way and I have seen them all in Men's Health Magazine (and others) as contributing authors or just quotes, etc....
They seem to have similar beliefs on training, health, and fitness in general
Afterburn I and II by Alwyn Cosgrove (haven't tried II but I am pretty sure he wrote a new one)
Mine is a spiral bound book so I am pretty sure I ordered it and not straight download, but I probably ordered from his website and not amazon??
Core Performance by Mark Verstegen (tried and liked)
The Book of Muscle (highly recommend) by Ian King and you guessed it....Lou Schuler!
Just my two cents, but I am taking notes on all these other programs/books that you are all recommending to try.....any thoughts out there about CrossFit? I had not heard of that until I got on this forum and then checked it out....thoughts?
