Sit and Reach Test

A sit and reach test is a way to measure someone's flexibility.

In Japanese, chouza-taizenkutsu 長座体前屈 refers to sitting on the floor with your legs stretched (chouza) and bending (kutsu) forward (zen) your body (tai).

In anime, sometimes there's an episode about a physical fitness test held in school, which may feature a measurement setup like this:

Character: Nishikata 西片
Anime: Karakai Jouzu no Takagi-san 2, からかい上手の高木さん２ (Season 2) (Episode 6)

• Context: a middle school student testing his flexibility.

Basically, you push this bench-like thingy forward, and your flexibility is measured according to the measurement tape set beside it. The further forward you can push it, the more flexible you're supposed to be.

Character: Kaidou Shun 海藤瞬
Anime: Saiki Kusuo no Psi-Nan, 斉木楠雄のΨ難 (Episode 10)

• Context: behold, the absolute flexibility of a high school student.
