Weights

A is a heavy object used by Rock Lee to train. Rock Lee wears the weights on his legs, and when he removes them, his speed increases. They have the word written on them.

In the first three games from the Naruto: Ultimate Ninja series, Rock Lee's weight appears as an item that can be thrown on opponents to temporarily reduce their speed. It is named in the first and second game and Weight of Determination in later games. In the fourth game onward it is replaced by a tag with the same effect, the weight having minor or no appearances afterwards.

In Naruto the Movie: Guardians of the Crescent Moon Kingdom, Rock Lee wears heavy bars that can be combined into weapons like a pair of nunchakus, a bō staff, and a long chain.
