Kourtney Kardashian has been working out like a mad woman, and it shows.
The most petite member of the Kardashian klan recently flaunted her extremely toned bum, svelte legs and flat abs while lounging in the sun wearing a pair of tiny black string bikini bottoms.
"Sunday funday!" she wrote in the caption.
Kourtney is relaxing after her rigorous morning workout, which she posted to Snapchat earlier today.
In the vids, she jumps rope as a warm up, then works her arms and core with handheld weights, a medicine ball and a barbell. Here's a snippet of her exercise routine:
Obviously, Kourt's hot body doesn't come from sitting on the couch eating Cheetos. (Worst news ever.)
Kourtney has certainly had a busy weekend.
On Friday, she and ex Scott Disick enjoyed a day exploring the Wizarding World of Harry Potter at Universal Studios with their kids Mason, 6, and Penelope, 3.
Then on Saturday, she and Disick were off to Nobu to celebrate her brother Rob Kardashian's 29th birthday along with other members of her famous family.
Kourtney's been spending an awful lot of time with her baby daddy of late, and fans are wondering if there's any hope of a reconciliation.
However, the brunette was recently spotted on a date with Diddy's son Quincy Brown, and Scott is rumored to be dating model Christine Burke.
Nevertheless, that didn't stop Scott from ogling his ex's recent nip slip on Instagram. But then again, who wouldn't?
How will he react to this latest post? We can't wait to see, because when it comes to Kourtney, it seems he just can't hold back.
