Warped wall

[4] In American Ninja Warrior Junior, the warped wall measures 13 feet (4.0 m), and will be completed at that height by the 13-14-year-olds.

The unique wall is equipped with two pocket levels, which will provide assistance to the other age groups.

Several obstacle course races, including Rugged Maniac[5][6] and Tough Mudder, have featured a similar wall albeit often with assistance available via ropes or teamwork.

[12][13][14] Several manufacturers of warped walls exist to provide gyms and private individuals with this obstacle.

[15][16][17][18] On American Ninja Warrior, there have been thirty-two women who have scaled the Warped Wall in Seasons 6–15.
