Snooki is still working on her fitness!

The "Jersey Shore" star, who has come a long way from the drunk party girl she was when the MTV show debuted in 2009, keeps flaunting her impressive physique online -- and it's still a work in progress.

"Getting more toned & defined !! #muscles #fitlife," she posted this morning, along with a photo showing off her sick stomach.

The reality star also posted a pic showing her intense workout regimen.

Hardcore, right?!

Snooks isn't the only star of her former reality show who's been hitting the gym either. 

Deena Cortese recently showed off her beach bod, posting that she had a "couple more pounds to lose!"
