Curious to know how celebrities squeeze fitness into their daily lives? Want to know the secrets of the stars? Bi-weekly our That's Fit fitness expert Fitz sits down with the celebs we want to know more about, and digs out their great and not-so-great methods to staying healthy

My guests this week are a bit dear to my heart, as they share the same passion for fighting as I do. Doug Anderson, a highly decorated Iraqi war veteran from New Jersey traveled across the world with Jimmy Smith, a young Mixed Martial Arts (MMA) fighter. Their journey had them test their skills against locals and various fighting styles, often styles they had never seen before. Always exciting, often painful, and always real....the Discovery Channel's Fight Quest stars went on an adventure of a lifetime and returned home with bruises and scars to show for it.

Fitz: Most folks dread the thought of even verbal confrontation. You guys volunteered to go fight a bunch of unknowns from around the world, many of which were yielding weapons you didn't know how to use! What scares you?

Doug: I was shot at in Iraq and had bombs explode 100 yards from me while there. None of that stuff ever scared me. But fighting like we did on this show was different. In Iraq I was part of a team; on Fight Quest I was alone. If I failed.....the onus was on me. I was always most nervous right before each fight, but I'd lose those nerves as soon as I got hit. It made me want to go running face-first into the other guys fist. Just to get it over with!

Jimmy: What scares me is not putting my best foot forward. It's OK to lose to someone better than me, but I hated the idea of losing to someone because I was fatigued or didn't put forth my best effort. As far as nerves go, you can't kill what's inside you. It's best to use those nerves to make you react; make you sharper.
