The sisters that waist train together, stay together.

Like siblings Kim and Khloe Kardashian, Kourtney Kardashian has taken up waist training, the exercise technique that requires one to wear a glorified corset while working out in hopes of slimming down and shaping the waist.

The mom-of-three, who gave birth to son Reign Disick last December, took to Instagram Monday to share a photo of herself in said device.

Aside from the Kardashian clan, stars like Amber Rose, Snooki and JWoww have all hopped on board the waist training bandwagon, claiming that cinching their waist while exercising helps burn calories and tone their tummies.
