Sorry but you probably don't see any difference between BB and physique. I see. Mavi can be called "hardcore physique competitor" but she is not bodybuilder. It is not the case of looks or mass but rather training, dieting, fitness activities, etc.
First off you are wrong from the fact "Body Building" is sculpting your body with weight training.
But you are also way off the mark as far as Mavi doing well in a Female Body Building Contest.
Mavi's has been working hard on her body.
While I think she could bring up her upper body and arms a bit She still belongs on a Body Building Contest stage.
Mavi's combination of looks and a killer body is what we need to see on a Body Building Contest stage.
She's attractive enough to stand out in a crowd and got enough muscle to keep body building fan's waiting to see more.
Mavi reminds me of some of the stunners on the body building stage of the past.
One that comes to mind right off is Sharon Bruneau.
Just look at these images, I've pulled from various recent Saradas posts and tell me with a strait face that isn't a body builder your looking at.
