Competitors must across three tilting frames with their hands to the landing platform. Competitors must build enough momentum to make a transition from one frame to the other as the frames tilt when they put their weight on the frames.
The three frames are arranged in a straight line, with the first two frames is positioned parallel to the competitor, while the last frame (the third frame) is positioned perpendicular to the competitor.This obstacle returned on American Ninja Warrior 7 during San Pedro (Military) finals, once again as the eighth obstacle. However, the third frame was removed.
The Swinging Frames also appeared on Ninja Warrior UK 2 as the fifth obstacle in Heat 4 (with a similar specification from San Pedro (Military) finals), and on Ninja Warrior UK 3 as the fifth obstacle in Heat 2 (with a similar specification from Dallas finals, except the perpendicular-positioned frame was placed as the first frame instead of the third).
