Kourtney Kardashian’s Makeup-Free Workout

Posted Wednesday January 15, 2014 2:50 PM GMT

Stepping back into the gym for her New Year’s slimdown, Kourtney Kardashian posted a selfie on Tuesday (January 14) to her Instagram account.

Opting to go without makeup, the “Keeping Up with the Kardashians” starlet looked intense in the photo, captioned, “Day one.”

And to prove how hard she’s working, Kourtney added a video for her Keek peeps from the treadmill as she put in a few miles.

It’s been a tough 2014 for Kardashian and her longtime boyfriend Scott Disick, whose father recently passed away just a few months after his mother’s death.
