No shoes, no shirt and no hands…no problem for Kourtney Kardashian!

The mama-of-three enjoyed her Labor Day on Monday by soaking up the sun, playing around with the kids and showing off her bikini body.

She took to Instagram to share a photo of herself riding a tricycle with no handles and still managing to look effortlessly #onfleek. She donned a pair of chic Westward Leaning sunnies along with a sexy, gold two-piece bathing suit that paid tribute to her hot bod' in all the right ways.

"Happy Labor Day!" she wrote before adding, "Wait, there's no emoji for a tricycle with no handles?!"

The 36-year-old has been putting in work to get her body back in shape after giving birth to her third child, Reign, in December.

In fact, just a few days before hopping in a bikini, Kourtney shared a photo of herself wearing a waist training corset while cleaning out her closet.  

"I am pretty much the queen of multitasking," she wrote over the weekend. "Obsessed with anything where I am doing more than one thing at a time, especially since I skipped the gym today. A little Saturday morning waist cinching and working on my posture while cleaning out my closet."

Meanwhile, other than giving body envy to her 23.9 million followers on Instagram, Kourtney had quite the busy weekend. She took Mason to visit an animal shelter to get "an education on why it is important to adopt and not shop."  Then, that night she enjoyed a "wild slumber party" with her kiddos.

The newly-single reality star appears to be filling up her days and enjoying lots of time with her children following her split from Scott Disick. The two broke up after nine years, and a source told E! News exclusively that Kourtney made the decision because she knew she had "to do what's best for the kids."

Despite the heartbreak, being single certainly looks good on her!
