Staying ripped to play Robert Pattinson
's big brother in Twilight
is all in a day's work for New Moon
hunk Kellan Lutz – who recently obliged screaming Twilighters at a recent fan tour in Atlanta.
When asked how he achieves his "amazingly hot body," the 24-year-old star – who helped
costar Taylor Lautner
get his ab-tastic bod – said, "I love push-ups. Those are the easiest thing for me."
After a fan requests that he show them his push-up skills (and another screams, "Take your shirt off!"), Lutz drops down on all fours and exhibits his physical prowess.
"I can do more than that," he says, "but that's too much for you guys!"– Janet Mock
