It's no secret that Kourtney Kardashian has been working on her fitness as of late, often times getting sweaty at the gym with one of her sisters. But now the mother of three is taking family fitness to a whole new level—literally.

Yesterday, Kardashian posted a photo of herself, oldest son Mason, daughter Penelope, and mom Kris Jenner's boyfriend Corey Gamble hiking. Talk about picturesque—the foursome is photographed from behind, looking out over one of Southern California's many lush, mountainous landscapes. For the excursion, Kardashian showed off her toned physique in figure-hugging black leggings and a cropped gray tee, while both her children are wearing T-shirts and shorts. Gamble also keeps it casual in track pants and a white tee.

"Hiking," Kardashian simply captioned the gorgeous shot. The family that exercises together, stays together! And it seems that their family hike tired the kids out—the same night, Kardashian 'grammed a photo of the book she was reading to her kids before bed, along with the caption "Goodnight."
