Following in her sisters' footsteps, Kourtney Kardashian is looking to train that already tiny waist of hers!
The mother-of-three, who gave birth to her third child, son Reign, just six weeks ago, took to Instagram on Friday to debut her post-baby body — and she looks incredible.
Wearing black leggings with a matching waist trainer and top, the 35-year-old happily posed in her massive closet (we're so jeal) to show off her killer curves.
"Gettin' it right, gettin' it tight...with my waist shaper! #waistgangsociety @premadonna87 @pre_shop," she captioned the post.
It's hard to believe the beauty looked like this just a few months ago!

Kourt's certainly not the first star to give the waist trainer a go. Sisters Kim and Khloé are huge fans, as well as these four celebrities!
The 36-year-old tried out her trainer while spending quality time with two-month-old daughter Chanel. "Real life candid pic..Training and watching my baby simultaneously.. The Coco way. Loving motherhood," she wrote.
