Kim Kardashian may not be Snapchatting her workouts, but she's still getting her fitness on.
The 36-year-old reality star took to Snapchat on Saturday to post a rare video of a morning workout, letting fans know that while she might not document it, she works out "every single day for over an hour."
"I never Snapchat my workouts, just because… I don't know why -- I'm just not Kourtney and Khloe," Kim said after posting a video of her intense workout during the family's Costa Rica vacation. "But it's like, if I don't Snap it, then it's as if it never happened. But I work out every single day for over an hour."
ET sat down with Khloe earlier this month, where she said working out with Kourtney and Kim helps her stay in the zone.
"I always thought that Kourtney was like a little bit of a p-*-*-s-y in the gym so I would never work out with her, because I'm a beast in the gym," Khloe said, adding that her older sisters "all compete fitness-wise." "But now we've worked out together and I'm like, 'Kourtney is badass.'"
