Kourtney Kardashian's Gym Selfie

They say a new year calls for a new you, but Kourtney Kardashian isn’t waiting until 2016 to kick off a sweat-inducing transformation. On Tuesday afternoon, the Keeping Up with the Kardashians star and mom of three took to Instagram to prove just how committed she is to leading a healthy lifestyle.

In the plainly captioned image above (“gym selfie”), the brunette beauty poses atop a yoga mag to snap a picture of herself dressed in her calorie-burning ensemble. Sure, Kardashian rocks a pair of high-waisted joggers and a matching sports bra with panache; however, it’s her ripped bod that’s catching our attention. The hard-working beauty flaunts a tightly toned midriff that, as we've seen, also looks nothing but fabulous in a gilded one-piece bathing suit (below).

Thanks for the #fitspo, Kourtney.
