Another great forum for strength and conditioning is the S&C sub-forum at http://mma.tv Or at least it used to be, I haven't logged on for some time, but at one time there were a lot of very knowledgeable folks on there sharing and trading advice and info. There was a good mix of people who were, for example, in college studying Kinesiology and who had a very scientific focus, professional trainers of MMA fighters, various athletes who train themselves (mostly MMA guys, for obvious reasons), etc. Some of the arguments could get pretty heated, but it's a good community of people who really care about strength and conditioning / health and fitness.
