This guy is a World class footbal/soccer player, the cardio sport if ever there was one.

I'm saying is look at most of the athletes that do hammerthrow or other types and they usually look a bit big, because there are limited options to having giant muscles. I will lay you ten to one those ladies up there are healthier than most world class body builders. Take away drugs and you have people who take diaretics, and use dehydration as a technique, or eat way too little, because that is what it takes to gain the muscle necessary but not the fat that comes with it. Body building is fairly new.
And thats why strong people in history were also portrayed a bit Large and fat. Whether Fictional, Like Porthos of the Musketeers, or real like Lois Cyr. Health has much less to do with weight than people not liking how it looks. In reality it is totally possible to be fat and healthy.
