About Addy Herman

Addy Herman is an American elite obstacle course athlete and media personality. She is best known for her performances on NBC's sports entertainment television series American Ninja Warrior, where she won the Women's Championship in 2024 and achieved multiple podium finishes. She has represented the United States in international ninja competitions and is a World Ninja League champion.

Herman began her television career competing on American Ninja Warrior Junior before transitioning to the main series at age 15, following a rule change that lowered the minimum competitor age. During her debut season at the National Finals in Las Vegas, she became the youngest woman in the show's history to clear the Warped Wall. In 2022, or Season 14, Herman earned the title of "Last Woman Standing" by advancing further than any other female competitor in the national finals. She followed this performance by winning the American Ninja Warrior Women's Championship in May 2024. During the filming of Season 18, Herman suffered a leg injury during the regional finals but completed the course to secure a third-place finish overall in the women's division.

Outside of the broadcast series, Herman competes in the World Ninja League (WNL), winning the tier-one championship title. In June 2026, Herman was selected as a member of Team USA to compete in Tokyo on Sasuke (the Japanese series upon which American Ninja Warrior is based). Competing alongside American athletes Vance Walker, Daniel Gil, and Josh Levin, Team USA won the international tournament. She has also placed on the podium at international obstacle events in France and Barbados. In Milan, Italy, Herman and fellow ninja competitor Noah Meunier set a Guinness World Record for the fastest completion of a couples obstacle course, finishing in 47.5 seconds.
