Keep up the hard work, Khlo!

On Monday, Khloé opened up about wanting to shed some unwanted pounds she put on over the summer. "Monday with @gunnarfitness!!! I am determined to get my pre-hamptons, pre- sympathy kourtney pregnancy weight off. Nothing good comes easy. Why do I blame Kourt though?!? Lol," she wrote yesterday with a workout selfie.

Nothing like being newly single to get your butt in gear at the gym, right?!
