Chef Robert Irvine

On the Food Network there is a show called Dinner Impossible, the chef is Robert Irvine. He looks to be in great shape, really built well. I searched and didn't readily find any info on him and his training, etc. I was wondering if anyone knows more info about him?

I know that he sure does know how to make some tasty lookin meals! Sorry, I'm no help.

There is also that femmy red head guy on the home makeover show. He does not look to lean but is for sure thick as hell.
