A steady diet of horse meat isn’t the only reason for his monstrous physique says Alistair Overeem. When Michael Schiavello pops the steroid question in an upcoming episode of The Voice vs. … , Overeem says he’s been accused of taking steroids since he was 17, but that’s not why he looks like he stepped right out of the pages of a comic book. He’s built like a superhero because he has great genetics and takes proper care of his body. Do you buy it?

The Voice vs. Alistair Overeem premieres on Friday, December 10, at 10:00 PM ET/9:30 PM PT on HDNet.
