There's a reason Kourtney Kardashian has been looking so good lately. The mother-of-three has been enduring some tough workouts, and she's got the Instagrams to prove it.

Kardashian took to the photo sharing platform today to share a picture of herself getting sweaty, and we have to say, her exercise regime looks intense. In the photo, a leggings and sports-bra clad Kourt is seen planking over a Bosu ball while holding push-up handles. We can only imagine the torturous (and effective) moves the Keeping Up with the Kardashians star completed with this equipment, but whatever she's doing is working.

"He kills me," Kardashian simply captioned the action shot. The "he" in question is trainer Don Brooks, who created the Don-A-Matrix method and has also worked with sisters Khloé Kardashian and Kylie Jenner.
