The Arm Rings (アームリング) were introduced in SASUKE 16 as the first obstacle in Stage Three. The competitor hangs from two rings on different-shaped sliding horizontal poles and must negotiate several separate rises and dips on each track. To make it through the obstacle quickly, competitors would do a strong push in the beginning to make it in the middle and would use the rings to bounce on the poles to get momentum. Although in place for nine tournaments, it served as more of an energy drainer as the two people who failed it (Nakata Daisuke and Yamamoto Shingo) failed due to injuries that made the obstacle difficult to complete. Following Urushihara Yuuji's kanzenseiha in SASUKE 24, it was replaced with the Roulette Cylinder.
It became the last obstacle at Muscle Park Odaiba's SASUKE section, replacing the Pipe Slider when it was redesigned in early 2009 before its closure the following year.
American Ninja Warrior
The Arm Rings returned in the Southwest and Northwest finals as the eighth obstacle on American Ninja Warrior 4, just after the Salmon Ladder. This proved to be a little harder, as some competitors ran out of energy as they were doing the obstacle. Also, the poles were at the same length, but the rises and dips on the poles were different than the SASUKE version. It was also used on American Ninja Warrior 6 in Denver finals. Several competitors who failed on this obstacle were Michael Zernow and Lance Pekus.
