Clad in a sexy black sports bra and low-waisted yoga pants, the reality TV star said that she's back on her workout grind after a seemingly short break from the gym.

"Don has been gone for 10 days but he is back," she wrote about her trainer, Don Brooks. "He almost made me throw up...love those kind of workouts."

The hardworking bombshell is no stranger to a sexy selfie, as she's become notorious for posting sexy shots of herself ever since her breakup from Scott Disick, the troubled father of her three children.

Keep on doing what you're doing, Kourt! We'll just try to keep up.
