Double gym selfie.

Get it, girls! Kourtney and Khloé Kardashian showed off their doubly impressive abs in a gym selfie that proves that the sisters are getting real when it comes to fitness.

In the photo, which both women posted to their Instagram accounts on Saturday, January 16, the pair are wearing matching black gym tights and sports bra tops that show off the contour of their toned tummies.

“Double gym selfie,” Kourtney, 36, captioned a version of the snapshot in which she’s sticking her tongue out. Khloé’s photo was equally impressive, with a nod to the mother of three.

“Gym selfie with the MILF,” the 31-year-old Kocktails With Khloé host captioned the shot on Instagram and Twitter.

This isn’t the first time that the sisters have shared behind-the-scenes looks at their workout routines.

In November, Khloé shared a video on her app that proved just how hard she works to stay in shape.

Clad in a Yankees cap, black running pants and pink Nike sneakers, the reality star alternates between sprinting, crunches and jumping jacks. She also, at different points throughout the video, lifts Kettlebells and dumbbells as her personal trainer Gunnar Peterson keeps a close watch.

“I would DEFINITELY feel worse if I skipped my daily workout,” she captioned the clip. “You never regret a workout, just the workout you didn’t make.”
