John Cena is 6 foot 1 and 251 pounds. Physically, he's built like a machine, with a sculpted upper body that boasts amazing size. Some fans have actually doubted that a body like that is possible without the aid of steroids, but Cena has always denied those allegations. He points to the fact that his body has been the same throughout his run, even after WWE brought in their drug testing policy in 2007. That's true. He has maintained amazing consistency with his physical condition. The truth is that he's just a physical freak of nature. He's genetically capable of a body that most people can only dream of.
