Mike O'Hearn is a bodybuilder and model who gained a worldwide fan base when he appeared as Thor in the American Gladiators series from 1989 to 1996.
He has also been featured on over 500 magazine covers, was Fitness Model of the Year seven times, and is a four-time Mr. "Natural" Universe title holder. Pretty impressive.
One thing he hasn't done is pose truly au naturel. That is until he posted the pics below. Next stop, playgirl.com?
