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.

This week I'm featuring one of the coolest guys in the world. A real life action hero who actually couldn't answer some of my questions, because he's been sworn to military secrecy. I love it! Bear Grylls is the star of Man vs. Wild on the Discovery Channel.

Bear was a survival expert in the British Special Air Services (21 SAS). He's obsessed with adventure as well as breaking rules and records. Bear is a brilliant outdoors man, built like a guy movie producers choose for their action flicks, and handsome enough to make girls want to watch him eat zebra guts. A fantastic combination for television.

To shoot each episode of Man vs. Wild, 33 year old, Bear gets dumped out of a helicopter in to the wildest most extreme regions in the world where tourists are likely to become stranded. He then gets to work trying to teach our sorry butts how to escape eminent doom. On Man vs. Wild, Bear has: thrown himself into both quicksand and an ice lake to demonstrate exit strategies, hidden from a sandstorm inside of a camel he'd previously gutted, and chowed down on everything from elephant dung to goat testicles. All for our benefit.

While interviewing Bear, I started the conversation off by telling him that I love the show, but spend half of the run time covering my eyes and ears. He didn't seem surprised. I often inquired about why he is willing to go to such extremes. He also didn't seem phased; unlike you and I....hiding inside of a camel doesn't seem appalling to him. The man is the real deal. He takes his job seriously and is literally willing to do anything to survive. I think I'm inviting Bear to vacation with me from now on.

Fitz: How did you get into this whole survival thing?

Bear: I was a survival expert in the Royal Marines. We had a tight unit and I loved it. I served twice.

Fitz: What kind of exciting missions did you go on in the military?

Bear: I can't tell you much, it's all kind of hush-hush! But in one of my unfortunate incidents, I broke my back in three places during a free-falling parachute accident in Africa.

Fitz: Ouch! I'm impressed that you recovered and came back for more. What kind of kid were you?

Bear: Oh God! I was always dirty and causing lots of trouble. Kind of like I am now.

Fitz: How did you end up with your own show on Discovery Channel?

Bear: I had done a television series about the French Foreign Legion in the UK. The people from Discovery Channel invited me to do Man vs Wild. They had to ask three times, because the first two times I told them no. I felt like they wanted some 'smart guy' and I was not what they were looking for.

I know. Isn't this a disgusting topic? Blech. How do I know this information you wonder? Well, a few days ago I had the luxury of speaking with one of the coolest men on television, Discovery Channel's Man vs. Wild star, Bear Grylls. Bear travels to the wildest locations around the world and teaches survival skills. So, just in case you get stranded in Antarctica some day......you'll know what to do.

Bear's complete interview will be featured in an upcoming Celebrity Fitzness Report here on ThatsFit.com, but in the interim I thought I'd share this fun information with you. A huge part of surviving in the wild is knowing what to eat and what not to eat. Bear discriminates against poisonous things, not disgusting things. Apparently neither should we.

This season he feasted on goat testicles. He was presented with them by some nomadic tribesman and contrary to Bear's initial projections, they did not taste like hard boiled eggs..................
