The competitor must cling onto a vertical log (60 cm thick) with their arms and legs, while it slides down a nine meter track to the next 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 proved 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:
SASUKE 29-30 Version
The Log Grip returned for SASUKE 29 as the second obstacle. However, the obstacle now had two ledges to hang on instead of the holes in the previous versions. For men the ledges were taller than the ledges women used. This modification made the obstacle extremely easier as many competitors were placing their hands on top of the ledges, providing extra grip. As a result, fewer people failed here.
SASUKE 31 Version
Minor modifications were made to the Log Grip in SASUKE 31:
- The track is steeper, and
- The drops are much larger than usual, which forced competitors to hold on tightly to prevent themselves from falling off the log.
American Ninja Warrior Appearances
The Log Grip made its first appearance on American Ninja Warrior 3 as the second obstacle, but the log was much thinner and the track was much shorter than the one in SASUKE.It returned in every qualifying region on American Ninja Warrior 4 as the second obstacle again. The log was thicker and made out of wood this time.
After a one year hiatus, it was back in Dallas on American Ninja Warrior 6, but with four handles (two on each side), instead of holes and only one drop. The handles version returned in Pittsburgh on American Ninja Warrior 7, but with two drops again.On American Ninja Warrior 8, the same version returned in Philadelphia. Later on that season, in Stage One, the Log Grip returned in the form of the Giant Log Grip. This version had four handles as usual, but:
- It has a 52 foot 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).
