I'm not especially impressed with Steve Kamb as a fitness guru. He has a writing style I find accessible, and doesn't seem to mind covering introductory material, which are pluses, but not outstanding in the fitness world. The gimmicky motivational approaches probably work for some people, but I find them silly.

I've found the forums to be a very valuable resource, though. Lots of knowledgeable people whose brains you can pick, and a structure for social support/accountability, which can be scarce in meatspace.
