Every, uh, smart reality-TV star knows the best way to capitalize on their fame is to branch out and become a multimedia brand, forever embedded in the American marketplace via spinoffs, books, and, yes, workout videos.

The “intense total-body workout,†obviously, includes a “bonus abs†section. Do people who watch Jersey Shore actually want to look like The Situation? Who knows, but he’d better hope this works out better for him than it did for equally hard-bodied but largely forgotten Real World cast member turned workout video star Eric Nies. [Page Six/NYP]
