Wow, there's something slightly creeptastic about looking at these pictures of Zac Efron hitting the gym, perhaps he's looking to bulk up for his remake of Footloose ? Hey, I'm not even saying he's hot, and he is 19 after all. Zac is certainly in the running for Next Big Thing  Status (heck, even Movie Star Shia wants to be him ) and judging from the clips I've seen of Hairspray, he's definitely got a certain charisma. Though the real star of that movie has got to be Nikki Blonsky -- in case you missed it, check out Buzz's interview with her and the film's director!  Now, back to Efron at the gym. Hopefully all his make-up  is waterproof!
