More important (to me if not the author) is overall health benefits. I don't really tend to conflate bodybuilding types of aesthetics with health. I don't want terrible athletic performance, but athletic performance is pretty far down my list of priorities. Also, I think it's very unlikely that the ideal dietary and exercise regimen for bodybuilding is identical to the ideal regimen for longevity or feeling healthy.
