Kim Kardashian recently called Kourtney Kardashian the "least exciting" sister to look at on an episode of Keeping Up With the Kardashians, but a Instagram picture Kourtney posted Monday proves her younger sister dead wrong.
The 39-year-old mother of three shared a photo of herself floating in a pool wearing a tiny, royal blue bikini, and it perfectly flaunts her six-pack abs.
"Perfect physique," one user wrote. "Most interesting to look at," several others commented, making a playful jab about Kim's comment.
And these insane abs aren't just genetics-Kourt puts a lot of work into her fitness. As recently shared on her website, the busy mom makes time to fit in 45-minute workouts at least five to six times a week.
Her personal trainer, Don Brooks, spoke with E! News after Kourtney gave birth to her third child about her workout routine. Apparently she used his "Don-A-Matrix method," which he designed like a game to make Kourt's workouts that much more fun.
"The Don-A-Matrix Method is set up to resemble a sports game format consisting of four quarters," Brooks said. "Each quarter has 3 sets of two different exercises, combined with rest or relief periods after each quarter. We use the resist-a-bands a lot-the bands are very effective for toning without bulking or injury."
Kourtney also swears by burpees and mountain climbers, according to a video she posted on her YouTube channel. And to warm up, she loves jump rope.
And because she's a Kardashian, she is often seen working out with her sisters. After all, what's a sister if not a built-in workout buddy?
Looks like Kim is going to have to eat her words.
