This preview of Leif Sundberg’s run has us very, very worried

We are WORRIED about Leif Sundberg. You need to watch this.

American Ninja Warrior returns with the fifth and final night of the season 13 Qualifiers on Monday, July 12. To help get us excited, the show released a preview of Leif’s run. And things do not go as planned.

After sailing through the Shrinking Steps and Double Down, Leif selects the Log Runner. And falls. He catches himself on the final log, the landing pad so close, yet so very far away.

The rules on the Log Runner state that you must use your feet to advance. Leif cannot simply reach out to the landing platform or try to fling himself there. He needs to stand up and run to complete the obstacle without disqualification.

So how the heck do you do that when your dangling above the water on a log that repeatedly spins you back down below it? That’s the question Leif is faced with in this video. It’s apparent that he doesn’t want to give up. But is this an epic save, or an epic fight that fails?

We’ll find out on Monday, July 12 at 8 pm EST/PST on NBC!
