Working on her fitness!

Kim Kardashian has been seriously hitting the gym lately—as is evident by her recent thong bikini pics—and today was no exception.

The 33-year-old stopped by a Pilates studio in Los Angeles to stay fit and wore a curve-hugging outfit for her workout.

Kim covered up her famous derrière in a pair of black capri pants and kept warm in a black jacket over her blue tank top.

Pictures of the E! reality star flaunting her figure on the beach in Thailand for a photo shoot surfaced just a day ago.

North West's mama strutted her curves in a teensy tiny nude two-piece swimsuit that highlighted, well, her assets. 

Kim was photographed in a variety of poses, including one picture from behind as she sat on the edge of a red boat (hello, booty!).

One thing's for certain, Kim is proud of her post-baby bod—and rightfully so!

The April Vogue cover girl was also spotted in a black bikini while she suntanned during her downtime in Thailand.

When you've got it, flaunt it, right?
