(TNS) -- NBC's "American Ninja Warrior" will slam back onto television on Monday with feats of derring-do more demanding than the last.
Host Matt Iseman (who began his career as a physician) says it's the background stories of the competitors that make the show.
"If it weren't for the stories, it would be two hours of people doing amazing, athletic things," he says. "But I think the reason this show resonates is because of the stories, because when you watch these people, they're not NFL players like (co-host) Akbar Gbaja-Biamila or great college baseball players like myself. These are everyday people who have jobs, who have families. And most importantly, I think the stories that resonate are the people who've overcome obstacles."
