A lot of work goes into being a pop culture sensation. You think that lying around on the couch is enough to make you internationally famous? True celebrities know that you need to keep moving, keep working, and look fabulous all the while (hey, you never know when a sneaky photographer might snap a picture). Feeling a little sluggish at the thought of hitting the gym? Maybe you need some famous fitspiration, courtesy of the sisters Kardashian.

With paparazzi dogging their every step and millions of fans demanding a constant stream of selfies, these women know that keeping fit is an essential part of the success puzzle. So the next time you feel like slacking off and skipping your workout, take a look at this fitness inspiration from the reigning queens of social media. You'll be ready to break a sweat and feel the burn in no time.

Kim Kardashian West
 


When you're running a media empire, maintaining a marriage, and raising two small children, you cherish every minute of free time at your disposal. Despite her decidedly cramped schedule, Kim always makes time to hit the gym and keep her body in top physical condition. And judging by her enviable abs and toned arms (not to mention that famous derriere), all that hard work is paying off (hey, you need to keep toned if you're going to rock the latest designer looks).

Kendall Jenner
 


Being a reality TV star demands you look your best at all times; being a runway and magazine model on top of that means looking picture perfect no matter what's going on. With all these demands to stay fit, healthy, and look flawless, you'd expect Kendall Jenner to practically live at the gym. Instead, the model works out smarter by doing intense core exercise to get the most out of her gym time. This video shows one of her favorite moves to achieve flat abs--just what you need when you're strutting your stuff on the catwalk.

Kylie Jenner
 


Kylie isn't quite the gym bunny her sisters are (most of her photos feature her being glamorous instead of embracing cardio), but she definitely makes sure to fit some fitness into her schedule, and her older sister Kim has been dragging Jenner to the gym whenever she can. Kylie may not love the gym like her sisters, but she has to appreciate the results (not to mention the selfie opportunities).

Khloe Kardashian
 


Unlike Kylie, Khloe loves the gym. The fashionista is devoted to her workout routine and frequently posts pictures of herself sweating. She's even taken her own struggles and turned them into inspiring fitspo for others, sharing her favorite tips and workout tricks. A regular fitness fanatic, Khloe (who has had weight issues in the past) seems to have found her rhythm and is loving the energy and health that comes with her gym visits. Looking drop-dead gorgeous probably doesn't hurt, either.

Kourtney Kardashian
 


The best revenge on an ex? Seize life by the throat and emerge looking hotter, stronger, and sexier than ever. At least, that seems to be the mentality that Kourtney Kardashian is adopting when it comes to her ex partner Scott Disick. The mother of three has been flaunting a devastatingly fit figure and catching the attention of the likes of Justin Bieber. All that time and effort in the gym has certainly paid off (and is there any satisfaction quite like looking magazine-ready when you run into an ex?). Your move, Scott.
