OKLAHOMA CITY - The Oklahoma State Capitol is the back drop to one of the most nail-biting reality shows on National TV - American Ninja Warrior.

"It's people mentally and physically battling a course and just being the best that they can, because we have people who train year round to compete on this course," said Christopher Zardus, Set Operations Manager.

This weekend, 125 ninjas will challenge the course.

One of the competitors is David, a youth minister.

"If there's a challenge, David's going to do it. He's not afraid, he's going to go for it," said his wife, Lindsey.

She said David has been working out two to three times a day, traveling to Ardmore regularly to train at a ninja gym there, improving skills like grip strength.

His family couldn't be more proud.

"He just has that fun heart, this energy about him and a show like this is right up his alley," said Lindsey.

His relatives even used their business to print t-shirts, a way to support David's journey.

On Friday, 125 ninjas will take a host at the course starting at 8:00, the top 30 will move onto Saturday night’s challenge and the top 15 from Saturday head to the finals in Las Vegas.

There’s a waiting list for tickets and you can sign up here.

We’re told people can stand around the perimeter; you just might not be able to catch all of the action.
