I still read and like FLEX but some issues are better than others. The ghostwritting is terrible but that's the way it is. I'm at the point where you can tell they're not keeping continuity in their info...the latest Dennis James chest article has him talking about building a big chest using flat bar bench presses...he wrote 3-4 articles a few years back AGAINST flat bar benching due to shoulder problems they incur, he'd use dumbells. They need to write SOMETHING and while I don't think it's very accurate to what the pro's actually do, it's probably somewhat close.
All the mags are pretty much useless after a year, but I keep buying FLEX just cuz. MD has a good interview every now and then (Vince Taylor, recently) and even MuscleMag has some good articles (the muscle chef articles)....it's not like you're going to learn anything mindblowing from the mags, but sometimes if you don't care to come up with original workouts, you can rip a few from FLEX. I just completed the 8 week strength program they had a few months back, and it's nice to just do something different. Plus, I felt the program was pretty good and all my major lifts increased...most of their programs are cookie cutter though, and the volume is pretty high.
Plus, if you ONLY read FLEX you'd have a pretty rose colored view of pro bodybuilding....then you come to getbig and find out the REAL deal, ha....oh well.
