First off, Kristin Cavallari looks fab! Whatever she's doing behind those gym doors is WORKING. Seriously, that body is ridic and we're glad she embraces it — she should be every bit of proud of it as she is!
Second off, where's the fire??
Kristin looked like she was all business, straight up BOLTING from her hard workout as she got into her car! Maybe she was just tired of having her picture taken when she was sweaty, or just maybe she's a superhero in disguise and had to go help someone in need!
Without talking to her, both explanations are completely valid!
Let us know your fitness secrets, girl!
