JWOWW is a partying pro. Not only does she know how to have fun until the wee hours of the morning, but she knows how to tackle the morning after, too.

Even after a wild night that ended at 3 a.m., Jenni doesn’t sleep in. Her crazy hangover cure is rising and shining — and then heading right to the gym!

Her fiancé, Roger, tweeted out a pic of her up and at ‘em on Saturday, writing:

Sure, she looks a little exhausted, but she’s still committed to working out, rockin’ that StairMaster!

Hopefully she hydrated with a shake before jumping on the machine! We admittedly don’t think about going to the gym after a night of drunken debauchery, but maybe we should try it sometime …

What do you think of JWOWW’s gym routine? Sound off below!
