At six months pregnant, Khloe Kardashian is still lifting weights like an ace — and she doesn’t care who knows it. On December 28, the mama-to-be shared a Snapchat video (via InStyle)that showcased her working out alongside sister Kourtney Kardashian.

With an all-business expression on her face, the Revenge Body With Khloe Kardashian star worked her famously buff arms and thighs using elastic bands and weights. The video also gave a peek at Khloe’s baby bump, which the reality star kept under wraps until she was good and ready to announce her big news earlier this month.

No doubt about it: Khloe is one buff mama-to-be. The workout videos come on the heels of Internet haters taking issue with the star’s exercise regime.

Khloe Kardashian Claps Back at the Haters Criticizing Her

After fielding comments that questioned the safety of her routine, Khloe fired back: “MY doctor and I communicate and my workouts are cleared and highly recommended.” Lift on, Khloe!

Khloe Kardashian has no time for your comments — especially ones that criticize her for working out while pregnant. The reality TV mom-to-be headed to Twitter to shut down anyone who might have something to say about her love for fitness during her pregnancy. “For the ones who think they are physicians all of a sudden, but MY doctor and I communicate and my workouts are cleared and highly recommended. Thanks kiddos! Don’t make me stop sharing s—,” she wrote, also sharing an article about the benefits of working out while expecting.  Khloe is a known workout fanatic. She’s even taken her love for all things exercise to the small screen having launched her E! series, Revenge Body with Khloe Kardashian, earlier this year, and a Season 2 of the show is premiering in January.

Though it hasn’t been all criticism for Khloe. In fact, following her pregnancy announcement last week, she thanked her followers for all their support.

Khloe recently confirmed that she’s nearly six months along and that fans will get to see more of her pregnancy on Keeping Up with the Kardashians. She shared with a fan that her pregnancy announcement will make its way onto the show: “Yes! It all happened during production so yes! Super cool to have that documented.” That seems to confirm some suspicions about this moment in a recent KUWTK teaser.

Oh, and haters, take note:
