Kim Kardashian is enjoying a late summer vacation in Punta Mita, Mexico with her husband Kanye West and children North and Saint, but her hard-earned bikini body isn't the only thing she's proudly showing off.
The reality star also took to Snapchat to put her moves on display, twerking up a storm in the pool. Now, Kim is not known to be the most graceful dancer, but even we'll admit she didn't do a terrible job this time around.

In fact, the improvement becomes extremely clear when you compare a clip of her underwater twerking in 2010 to that of today. Clearly, somebody has been putting in the work!
Here she is back in the day, with her sad, uncoordinate twerk:

And today, making that booty clap so confidently that we seriously wonder if she hired a double:

As you can see in the caption, Kim credits celebrity makeup artist and her look-a-like Hrush Achemyan with teaching her the art of the twerk. 
A+ for effort, Kim!
