You do you, Kourt! Kourtney Kardashian is getting the hang of this whole Snapchat thing. The Keeping Up With the Kardashians star used the social platform to take a gorgeous photo of herself on Tuesday, March 29.

The reality star has been documenting her workout regimen since joining Snapchat on March 16. When she's not doing push-ups in the gym, she's running up hills and chasing after her adorable kids — Mason, 6, Penelope, 3, and Reign, 15 months.

Staying fit was one of Kardashian's New Year's resolutions. "I haven't made New Year's resolutions for as long as I can remember. However, since I have made a lot of changes this year, writing down my resolutions felt important to do," she posted on her website last December, appearing to reference her split from Scott Disick. "[I will] continue on the workout mission that I started this year."

Kardashian and Disick have remained cordial since breaking up after nine years. Disick even makes the occasional cameo in her Snapchat stories. On Monday, he joked that the two were getting back together. In a second video, he playfully grabbed Kardashian's breast.
