The Unit -- Shirtless, Ripped, & Twisted Sideways

The Situation's GTL bestie Jonny "The Unit" Manfre took time out from fighting with Snooki on "Jersey Shore" and flaunted his buff & hairless strength at Muscle Beach in Venice Beach on Wednesday.

The Unit -- alongside his smoking hot XXX girlfriend Amia Miley -- proved his jacked up muscles weren't only for show, and even held himself up sideways off a bar.
