It's all about the abs! Khloe and Kourtney Kardashian yank down pants to flaunt abs

It's amazing what a few months of dedicated gym-going can do. Just look at the Kardashian sisters, Khloe, 31, and Kourtney's, 36, washboard abs as proof.

The women couldn't help but show off their efforts in an Instagram snap, both pulling down their black pants to reveal their taut tummies.
Alongside Khloe's pic, she wrote: "Gym selfie with the MILF. And yeah, considering Kourtney's given birth to three kids, this is a serious body.

Earlier this month, Kourtney said the gym was helping her to cope with the break-up from her ex, Scott Disick.

Kourtney and Scott split in June and have Mason, six, Penelope, three, and one-year-old Reign, together.

Meanwhile Khloe said she used fitness to deal with her split from estranged husband, Lamar Odom, who is currently in a rehab.

In April, she said: "When me and Lamar were having issues, I decided to channel my energy into working out.

The gym was my only refuge."
