Transcript for Bobby Bones’ new show celebrates the lives of unsung American heroes
Reporter: Bobby bones is taking a beating. Literally putting his life on the line. Traveling to far-flung places around the country, seeking out people in unique circumstances. This self-deprecating star of country music radio, mentor on "American idol," former "Dancing with the stars" champion, has a new gig -- a show called "Breaking Bobby bones." It airs on national geographic, owned by Disney, the parent company of ABC news. Where did you come up with the name "Breaking Bobby bones"? Why that concept for the show? People will come for the hook. The hook is, watch if I die, watch if I get hurt, watch if I quit. If they come for the flash, maybe they'll stay for th stories and heart and perseverance and be inspired, be motivated by these different heroes, these people's stories. Reporter: Stoies like Loni Bedwell's. Lonny was shot in the face with a otn, he's blind, yet he inspires by climbing mountains, Whitewater kayaking. I managed to stay straight until -- oh my god -- this happens. Bobby! It started with finding folks who had been through a lot of adversity. Me in my life, I've been through a ton, really rough childhood. When I wanted to travel around and find their stories and showcase them, turned out a lot of them had extremely interesting lives or hobbies or skills. And so I was like, well, why don't I also try what they're doing? I was getting their story, I was also doing and showing how uncomfortable that I can be at the same time. But for me to get people to the story, I needed something like "Break Bobby bones." People to go, let's see what this idiot's up to. Reporter: Bobby wanted the show to focus on a slice of life not often captured on social media, celebrating unsung American heroes. I wanted to highlight a lot of peoe throughout middle America who kind of don't get the look because they're not in L.A. Or New York. If you're not high flying, living the life, smiling, flexing your money, then you're not being seen. And so there are a lot of people who feel alone because they don't feel like anyone relates to them. Reporter: One of the roughest experiences, playing ice hockey on sleds. With Ralph, a wounded veteran from Denver, who was injured in Afghanistan. He lost both of his legs serving our country. He came back, he didn't know what to do. He admits on the show with me that he was suicidal when he came back. He goes over, he's healthy. He comes back, he doesn't have legs anymore. What does he do, where does he find his life now? Turns out there's something called sled hockey. And he's on the U.S. Paralympic team now. He'd never played hockey in his life, but he learned how to play hockey through a video game, he trained, made the team, they want to go medal. I need America to see that story. I need America to know what he's been through, what they're going through, they're not alone. Reporter: His empathy stems from his own troubled childhood. A story he shared with "Nightline" two years ago. I come from a really small town of 700 people in mountain pine, Arkansas. I grew up without a dad, my mom was an addict who ended up dying in her 40s. I needed to break the cycle. From an early age I knew that I had to get an education and get out. First kid to graduate high school in my family. First to graduate college. I needed to get out to show others they could do it. Reporter: His personal mantra made it to the cover of his second book. Fight, grind, repeat. I needed words that I could go, this is it. The fight is identifying the goal. Here's my fight, this is what I want to do. The grind is the hard work you have to put in every day even though no one's looking. There's no glory in the grind. Repeat is, it doesn't work out the first time. When it doesn't work out, can you repeat and do it again? At one point you're dangling over the grand canyon. Reporter: Anyone scared of high places like Bobby freely admits, the most terrifying moment comes here. My leg is shaking like crazy. I'm a little -- okay, I'm a lot scared. You got this. Here we go. One, two -- oh -- oh-oh -- I don't think -- Okay, go ahead and sit down. Felt like something undid that shouldn't have undid. What is happening here? Bobbi, stop right there. Stop right there. Whoa, whoa, what's going on? Oh my go What is going through your mind as someone who is afraid of heights? I hated it. I'm not going to sit and act like it was fun, it wasn't. I didn't sleep the night before. This guy, Mike, he had been in prison, he had been in gangs, pretty much people had written him off. He had written himself off. But he had found something called rope access, another job I didn't know existed until this show. But what he does, he builds rope rigs and he goes to places that humans can't go with a crane or a drone, and he climbs up there. It just so happened when I met with him, he was underneath a skywalk of the grand canyon, which meant I had to hang 4,000 feet on a rope. And there's one part of the show -- Oh, god -- My leg is shaking so bad, you can see my foot not able to actually get a grip. That was tough. Reporter: Paying it forward is the underlying theme. Marina, who moved to Seattle to go to school and be a commercial diver. To be honest, I didn't know what that was. I thought you put on a snorkel, kick some fins and that's it. This is scary. Make sure to breathe. So I go, I put on 100 pounds of equipment. They send me down to the sea I'm doing construction. But finding her story where she took care of her mom before her mom died of cancer, she slept in her truck the last weeks of school so she could save up the money as she went to school to make the move to actually get a job. And so at the very end the episode -- Reporter: Actually, you're going to have to watch next week to find out what happens to marina. But given everything Bobby has been through, you can bet it's going to be good. I don't have some amazing skill or talent. I don't show up every day -- I control what I can control, my work ethic and attitude. If I don't have that, I have nothing. I've built a career and a life focusing on that. Focusing on the things I can control. For someone who's been so successful at being in control, Bobby's getting married later we're just wondering if that control thing might slip a bit. "Breaking Bobby bones" airs on the did national geographic channel.
