American Ninja Warrior season 1

The season was hosted by Blair Herter and Alison Haislip and the finalists were sent to Japan to compete in Sasuke 23.

Levi Meeuwenberg was the "Last Ninja Standing," meaning he made it the furthest of any American competitor on Sasuke 23.

The ten contestants with the top times go on to compete in Sasuke 23.

Challenge #1: Competitors must shove 10 large slabs across a 50-foot (15 m) distance and arrange them in a pyramidal structure while a bungee cord (with a big tire on the end) is strapped to them.

Then, they must walk across two logs with a heavy barrel lifted high over their head.
