Kourtney’s Sexy Workout Selfie – ARTICLE

Kourtney Kardashian is fresh off a trip to St. Barts, but that doesn't mean the 36-year-old mom of three is taking a jetlag-induced workout break!

The newly single reality star posted a sexy selfie in exercise gear on Saturday.

"No breaks," Kourtney – who gave birth to her third child in December 2014 – captioned the pic, which shows the star in a black sports bra paired with tight black capris (abs fully on display).

Since her split from Scott Disick in early July, Kourtney has been hitting the gym and showing off her results on Instagram.

Last week, the sexy mom proudly displayed her bikini body in a poolside shot captioned, "Troop Beverly Hills."

Kourtney and Scott, 32, split over the Fourth of July weekend, after nearly 10 years of dating.

They welcomed their third child -- son Reign Aston – just eight months ago. They also have a son, Mason, 5, and a daughter, Penelope, 3, together.
