Kourtney Kardashian isn’t shy about her banging breakover body.

The reality star posted a gym mirror selfie on Tuesday, and she looks fabulous as ever after the sweat session.

Kardashian, 36, wore her hair in a messy ponytail and rocked a black sports bra and matching yoga pants.

As it turns out, staying fit is one of her New Year’s resolution: She wrote in a post on her website/app that she aims “to continue on the workout mission that I started this year,” along with “to continue to strengthen my relationship with Jesus,” “to refocus my priorities, making sure that ‘me’ is high on the list” and “to allow myself to feel my emotions.”

The mom of three has been single since splitting from longtime love Scott Disick in July, though sources say she’s hooked up with Justin Bieber, a close friend of the family.

Her little sister Kylie Jenner recently spoke about how the pop star has helped her navigate fame, telling Elle U.K., “He gets me, and every time I see him he always sits me down and is like, ‘Are you OK? You’re amazing. You can get through this, just stay true to yourself.’ He helps me a lot.”

On Monday, Kardashian posted an Instagram collage reflecting on her roller-coaster year.

“Whatever happened over this past year, be thankful for where it brought you. Where you are is where you’re meant to be,” she wrote.

And a preview from the next episode of Keeping Up with the Kardashians shows Disick, 32, tearfully apologizing to Kardashian, her sisters and mother for his hard partying.

“I’ve apologized to Kourtney a hundred times, but I’ve never apologized to like all of you for letting all of you down and embarrassing you guys,” he says. “”I understand I need to help myself way before I can help her or my kids or whatever, but it’s just been a really hard time going from like having all of you guys to having nobody, you know?”
