But to excel on the "American Ninja Warrior" course, he said, it isn't just pure strength.

"What has surprised me is the fact that you don't have to really be muscular. If you look at the obstacles, you would think a person has to be a total Lou Ferrigno or Arnold Schwarzenegger. They have to have some big muscles, but no, not really," Tyrone said.

That may be true, but Glenn said Tyrone has transitioned seamlessly to the ninja warrior world, even climbing the Warped Wall with little trouble.

"We blinked, and he was at the top of the wall like, 'That's it?" Glenn said with a laugh. "It was so cool to see him up there, just hanging out, standing on top of the wall. I told him, you know, that's not going to be a problem. This is one thing we're not going to worry about."

The physical aspects are only one part of the battle. The mental aspect of the game, just like in football, can be the downfall for competitors, Glenn said, but Tyrone said his experience playing in front of thousands of fans in NFL stadiums will help him keep a clear head in front of the crowd.

"I'm used to learning how to block images and distractions, so it doesn't distract me. I think I'll still use the same kind of mentality. I'll know people are there, but not to the point where I'm distracted by them," he said. "I'll probably be more distracted by the water that's on the bottom than the people on the side. I don't want to fall in that water."

But when it comes to getting into the right state of mind, it's all about a winning mentality.

"I won two Super Bowls and now I have the opportunity to win a championship as a ninja warrior on that course," Tyrone said. "You know how we do it as Patriots. We're only in it to win it."
