Kim Kardashian West might have spent the past few days showing off her incredible post-baby bikini body, but she’s not the only Kardashian who has abs for days. Older sister Kourtney Kardashian is giving Kim a run for her money in this skimpy gray bikini.
The 37-year-old took to social media on Sunday to show off the results of her hard work in the gym. Kourtney lounged by the pool in a gray Amaiò Swim bikini ($350; amaioswim.com), smiling with a pup on her lap in one sweet photo (above). “Just call me the dog whisperer,” she wrote.
Over on Snapchat, the Keeping Up with the Kardashians star shared even more shots from her picture-perfect pool day. In one cute clip, the ultra-fit mom clinks glasses in a pair of mirrored sunnies before enjoying a refreshing drink.
The mom-of-three also shared a Snap of herself from behind, walking with her 1-year-old son Reign.
