Snooki “can’t wait to train insane again”.

The pint-sized reality star is expecting her second child, a daughter, with fiancé Jionni LaValle.

And Snooki said one of the main things she is looking forward to about giving birth is being able to return to her rigorous workout regime.

Sharing a flashback picture of herself flexing her arm muscles while lifting a weighted bar at the gym, Snooki tweeted: “Can’t wait to train insane again!”

Following the birth of her son Lorenzo, now two, Snooki shed a dramatic 50lbs and entirely transformed her appearance thanks to regular workout sessions and healthy eating.

"Dancing is an amazing workout," Snooki said previously. "It's helping me keep my legs and everything else toned. I'm a size 0 and proud of it!"

"I used to hate going to the gym, but now I love it. I lift very heavy weights, and I'm strong."

Meanwhile, Snooki’s little boy Lorenzo enjoyed his first playdate with the reality star’s best friend Jenni ‘JWoww’ Farley’s daughter Meilani on Tuesday.

Jenni posted a picture of Lorenzo holding the feet of little Meilani on her Instagram page.

“Counting toes,” Jenni captioned the shot.

And Snooki was quick to comment on the super cute picture.

“OMG how adorable are these two together?!" Snooki wrote on her blog. "Lorenzo’s already protecting Meilani and I’m obsessed. They’re so going to be besties!!"

Meilani is Jenni’s first child with her fiancé Roger Matthew.

Jenni recently revealed that Meilani’s birth will be featured in part on the upcoming fourth season of their reality show Snooki & JWoww.
