Have you heard of the stunning Katelyn Runck, the fitness model from Dakota? This babe’s already a pro bikini athlete, online coach, and the boss lady of Lifestyle Savvy & Boutique.

But before she blew up, she was doing runway modeling with Factor Woman in Chi-Town. Bet she wasn’t rocking those massive knockers back then, though. We mean, we’re pretty sure each implant is like a liter or something. Insane, right? And don’t even get us started on that booty of hers, it’s straight up delicious.
