Having moved on from her heavy drinking and partying days as a cast member of MTV's "Jersey Shore," Nicole "Snooki" Polizzi is documenting her new life as a mom and fitness fanatic on Instagram.

After revealing her startling 42-pound weight loss to US Weekly back in January, the diminutive 25-year-old television personality has kept up her training regimine.

In a Tuesday Instagram photo, Polizzi showed off the results of her hard work, flashing her biceps for the camera.

"Getting more toned & defined!!" she captioned the photo. "#muscles #fitlife."

"#fitmom #damnproud," Polizzi captioned another bicep-bearing photo.

"I have a lot of energy because I work out so much and the endorphins put me in a good mood. And when you're skinnier, you feel so much better about yourself," Polizzi said of her weight loss.
