You want to see a REAL beast? Look at this guy here, from SASUKE!

One of those things that looks easy but is actually extremely hard. Especially stage 3. Those domino mat things? Holy s'hit.

Not to mention that the female course is built around balance than physical strength. And they still have the 4th stage the same. o.o

Wait, you mean the male-version of Ninja Warrior. That's because it was some of the earliest Ninja Warriors. In some of the latest ones, they revamped 4th stage too. @_@

Mis-understood. Yeah, female version is more suited for balance than strength, but in 3rd stage Ninja Warrior (male version), you can see that there's a lot of parts which involves flexibility, balance, and coordination as well.

EDIT: And yes, those dominoes are definitely hard. I gotta admit to that.
