Snooki of MTV’s “Jersey Shore” was a cheerleader in high school but, in recent years, her weight has ballooned mostly because she has a chaotic lifestyle, eats junk food and ingests large quantities of alcohol. Now, curvy Snooki is a bit less curvy.

The reality star, who is getting ready to head to Italy to shoot part of season 4 of the reality series, has recently unveiled on Twitter that she’s found a new “hobby”: working out at the gym.

Clearly, spending more time working out and, one may assume, keeping a tab on the daily calorie intake, is already paying off for the diminutive star, as PopEater also notes.

“The reality star guidette has been hitting the gym to tone up her 4’9” frame. She told the mag that just before season one of Jersey Shore hit the tube, she weighed 100 lbs. She soon found that the cast’s intense partying would leave its mark on her petite figure,” the e-zine writes.

“Recently, according to Snooki’s twitter page, she’s been putting a little extra ‘G’ in her gym, tan, laundry (GTL) routine. But the pounds don’t come off unless you’re willing to make some major sacrifices – as Snooki found out,” PopEater notes.

Now that she’s put in the extra time at the gym, Snooki can brag: and this is just what she does in a photo she uploaded of herself in Twitter, looking visibly more slender and toned.

“as everyone’s planning their night at the club, I’m wondering when Golds [Gym] closes lol #motivated,” the star tweeted.

She’s so motivated, she even went on a diet, as she reveals in another tweet. “water is my new best friend. #dieting,” Snooki tells her followers.

“Dying at the gym! Can’t feel maaaa legs!!! (Forest Gump Voice) Jennnayyyy help mehh,” she tweeted later, asking for co-star and friend Jenny JWoww to come save her from her personal trainer.

As we also reported a while back, Snooki has tried before to get in better shape but she didn’t manage to stick to the plan. Even though she went on Dr. Siegal’s Cookie Diet, Snooki did not lose any weight – on the contrary, actually.
