Strong body doesn't only come from body training but also from foods. I think healthy body comes from the foods you eat. Proverb says "You are what you eat". Your body-training also plays a big role in maintaining health. If you know Shaolin, then you must know that Shaolin monks don't eat meat. They are vegetarian and they get strong by training, too.
Just now, I found a video at youtube that shows you those famous vegetarian and vegan bodybuilders, athletes, sportmen and sportwomen.
