The reality star is also meeting with senior adviser Jared Kushner on Wednesday to discuss prison reform.

Kim Kardashian West is obsessed with bikini selfies -- and for good reason.

The Keeping Up With the Kardashians star continued sharing a string of stunning vacation pics over the weekend, most of which featured the fit mother of three wearing an assortment of two-piece swimsuits.

She has her trainer to thank for her fit physique, and shared how she put in a lot of hard work and some major discipline to get her body back. 

"Shout out to my trainer @fitgurlmel who really changed my body," the 37-year-old reality star wrote alongside a bikini selfie that showcased her taught tummy. "When I wasn’t happy with what I saw back in the mirror, I spent a whole year training so hard -- five or six days a week -- putting in a lot of work and changed the way that I [ate]."

Kim added that while the workouts were "crazy" and she despised doing sprints, she feels "so much more confident" these days with how she looks.

"There’s such a noticeable difference," she continued. "I am firm and less cellulite and so much more confident. SO THANK YOU for waking up at 5 a.m. to do crazy body building workouts and sprints that I hate and putting me on to this lifestyle."
