The mother of Mason, Penelope and Reign Disick also showed off her skills on a tricycle. "Happy Labor Day!" the 36-year-old reality star Instagrammed to her 23.9 million followers. "Wait, there's no emoji for a tricycle with no handles?!"
This isn't the first time Kourtney has flashed her bodacious bod since her split from Scott in July.
After her bikini-clad St. Barts vacation with the Kardashian-Jenner clan, Kourtney posted a selfie of her posed in ab-baring workout gear. "No breaks," she captioned the pic.
Kourtney's mother, Kris Jenner, recently praised her oldest daughter in Haute Living magazine, following her daughter's breakup.
