Ow ow!
There’s no doubt that Kourtney Kardashian has been workin’ on her fitness!
The mom of three is in the best shape of her life — so much so, that even 21-year-old Justin Bieber has taken notice!
Well, after half of a year of trying to get her littlest sis Kylie Jenner, 18, to join her for a sister sweat sesh, the gym date finally went down on Saturday.

We hope she could keep up with the 36-year-old!!
Kourt posted on her on page saying she finally convinced baby Jenner to get in the gym:
Hey, Kylie has been busy selling out her Kylie Lip Kits and stuff… Give her a break!
Regardless, these ladies look fab!!!
