Most sports magazines promote very unhealthy body shapes. And often they don't report on important athletes because they don't look good. That's why I cancelled my Runner's World subscription decades ago. Once in a while I get a glimpse of their new covers and they seem to be getting worse. Like that cover "the raise of the skirts." It's more about fashion than sports.
The Runner's World cover is always a pretty girl, but I don't think that's the case of the content, e.g. Craig Pickering (100m sprinter) looks like a perfectly normal person but he's in there almost every month. Jessica Ennis and Kate Dennison have normal healthy body shapes.
I've always found Men's Health to have pretty ideal male physical forms on the cover. They've had Obama on the cover, Beckham, and sometimes the cover man isn't even shirtless. In fact, when I'm at the gym talking about goals, I'll sometimes say "more like Men's Health, not MuscleMag".
