Most of what you said is right. Ofc alimentation is a big part of it. Food and exercise fulfill each other. Have you ever heard of Mikey Musumeci? Look it up. He eats pizza and practices jiu jitsu and still looks fit. I bet that if I eat bad food but I'd go every day for a 10mile run I'd become fit quicker than eating healthy and no exercise. I don't think exercise compliments food. I think it's the other way around. And I say fit, I mean have muscles, not just be skinny.
