Sure. Many of those instagram fitness models would look incredibly hot no matter what kind of training they did. There are girls in their 30's who have an amazing body with minimal exercise and/or diet. Sure, they are a small minority, but these genetics exist (and sometimes they are combined with genetics for an amazing facial structure to go along with). And it's always been those girls that became models, not girls with average genetics who have to struggle with their diet and exercise to look good.
