The Log Grip (ロッググリップ) is a First Stage obstacle implemented with the SASUKE 18 redesign after Nagano Makoto's kanzenseiha.

Competitors must cling onto a vertical log (60 cm thick) with their arms and legs, while it slides down a nine meter track to the landing platform. The log contains many small indentations to provide some grip.

The track is similar to the one previously used for the Sandan Rolling Maruta, but:

  • The drops are bigger and the track is longer
  • The drops are closer together, almost eliminating a chance to recover from the previous drop.

SASUKE 21-25 Version

In SASUKE 21, the Log Grip was modified. The actual log was placed lower to the platform and a new mechanism was engineered where once a competitor applied his or her weight, the log would start down the track.

This was proven to make the log much easier to start, but in contrast, competitors would fail more because of the speed and shock of the drops.

It was the second obstacle initially, but became the third obstacle from SASUKE 22 to SASUKE 24, when these three obstacles took its previous position as the second obstacle throughout the three tournaments:

In SASUKE 25, it was moved even later in the course, shifting to the fifth obstacle. Since being moved later into the course, competitors would show fatigue and fail. It was removed after SASUKE 25.

SASUKE 29-30 Version


The Log Grip in SASUKE 29

The Log Grip returned for SASUKE 29 as the second obstacle, replacing the Rolling Escargot from the previous tournament. However, the obstacle had two ledges to hang on instead of the holes in the previous versions. For male competitors, the ledges were taller than the ledges used for female competitors. This modification made the obstacle extremely easier, as many competitors were placing their hands on top of the ledges, providing an extra grip. As the result, fewer competitors failed here.

SASUKE 31 Version

Minor modifications were made to the Log Grip in SASUKE 31:

  • The track was steeper, and
  • The drops were much larger than usual, which forced competitors to hold on tightly to prevent themselves from falling off the log.

Those who cleared had serious bruises from holding onto the log. It was replaced by the TIE Fighter in SASUKE 32.

American Ninja Warrior Appearances

ANW3 Log Grip

American Ninja Warrior 3's Log Grip

The Log Grip made its first appearance on American Ninja Warrior 3, as the second obstacle during qualifying and semifinal, but the log was much thinner and the track was much shorter than the one in SASUKE.

ANW4 Log Grip

American Ninja Warrior 4's Log Grip

Then, the obstacle returned as the second obstacle in every qualifying region on American Ninja Warrior 4. This time, the log was thicker and made out of wood.

ANW6 Log Grip

ANW7 Log Grip

American Ninja Warrior 7's Log Grip in Pittsburgh

After one season hiatus, the Log Grip returned as the second obstacle in Dallas on American Ninja Warrior 6, but with four handles instead of holes (two on each side) and only one drop on the track. The handles version later returned as the second obstacle in Pittsburgh on American Ninja Warrior 7, but with two drops again.

ANW8 Log Grip

American Ninja Warrior 8's Log Grip in Philadelphia

ANW8 Giant Log Grip

American Ninja Warrior 8's Giant Log Grip in Stage One

On American Ninja Warrior 8, the same version of the Log Grip from the previous season returned as the second obstacle in Philadelphia. Later on that season, the Log Grip returned in the form of the Giant Log Grip, as the third obstacle in Stage One, replacing the Silk Slider from the past two American Ninja Warrior seasons. This version had four handles as usual, but:

  • The obstacle has a 52 feet long track, with three drops, and a dismount onto a small landing pad, floating in the water.
  • The log also twisted around at the end of the track.
  • Competitors also had to time their landing correctly or let the log stop swinging to land.

This version of the Log Grip was proven to be much lethal, as several competitors either lost their grip or couldn't time the dismount properly. Although only 12 competitors failed on this obstacle, it eliminated several top competitors (e.g. Jo Jo Bynum, Adam Arnold, Meagan Martin, Brent Steffensen, Kevin Bull, and Jamie Rahn).

On American Ninja Warrior 9, the Giant Log Grip was replaced by the Double Dipper.
