At the center of the over-the-top action/fantasy series, Sorbo plays the half-man, half-god of ancient Greece, protecting humankind from capricious deities, evil centaurs, fire-breathing dragons and other assorted bad guys. That translates into a lot of kick-boxing, sword-fighting and additional acts of prowess worthy of a demi-god. Sounds exhausting, but for Sorbo, 38, who performs many of his own stunts, such feats are all in a day's work.

And, the flaxen-haired actor says, he tops off those long days on the set with a strenuous workout, keeping those muscles -- and his 43-inch chest -- up to snuff. "I go to the gym and spend 90 minutes there every day, after a 14-hour day. I work out all the time," the Minnesota native told New York's Daily News.
