Move over Greg Valentino, there's a new man with exploding arms.

From MSN.com:

Massachusetts bodybuilder Moustafa Ismail eats 7 pounds of protein, nine pounds of carbohydrates and 3 gallons of water each day to help maintain upper arms that measure 31 inches around - as big as a small man's waist.

Skeptics say there must also be steroids or some other artificial means behind Ismail's beyond-bulging biceps and triceps, and Guinness World Records is waffling on whether to recognize him.

But he insists they are all natural, the result of a punishing workout regimen he started after a guest at his uncle's wedding in his native Egypt mocked his overweight frame.

"They call me Popeye, the Egyptian Popeye," Ismail, 24, said while working out in the Boston suburb of Milford. But unlike the cartoon character, "I like chicken, beef, anything but spinach."

Sorry, Moustafa, but somehow I'm just not convinced.
