On Sunday, Kourtney took to her Instagram Stories to share several clips of herself suspended in the air and working on a pilates routine! The Poosh founder looked fit AF going up and down on the contraption, and using her body weight as resistance to stay tight and build muscle.

Ch-ch-check out the amazing athleticism (below):

Wow! So that’s how she keeps her body looking so good for all those Poosh ads!

Kim also got in on the action, showing off a couple clips on her own IG Stories, as well as giving a shout out to pilates instructor Jesse O’Hara for all the help in, uh, showing them the ropes (literally):

Love it!
