体育授業「おりられないブランコ」　Physical education class "A swing you can't get off of"

【シチュエーション動画】

「先生、補習を受けさせてください...」
「放課後、体操着に着替えて体育指導室に来なさい。」

****が補習で受ける体育の授業。
補習内容はブランコ運動。
ブランコは揺らす運動器具。
だが今日の補習では、
揺らさずに耐える体幹トレーニング。
基準値の範囲を超え揺れた場合は
追加補習が待っている。
とは言え、誰でも出来る程度の内容。
ブランコでじっとしていればいいだけ。
少し違うのは、立ち漕ぎ姿勢の状態で
手足をブランコに括りつけ行う。
たったそれだけのこと。
これは、****に
無事卒業して欲しいと願う体育教官の
優しく甘いムチの補習授業。

"Teacher, please let me take a supplementary lesson..."
"After school, change into your gym clothes and come to the gym instructor's office."

A physical education class that female student take as a supplementary lesson.
The supplementary lesson is swing exercise.
A swing is a swinging exercise equipment.
However, in today's supplementary lesson, we will train our core to endure without shaking.
If the shaking exceeds the standard range, additional supplementary training will be required.
That said, the content is something that anyone can do.
All you have to do is stay still on the swing.
What is a little different is that you are in a standing position and your hands and feet are tied to a swing.
That's all.
This is a supplementary lesson in which a physical education instructor who wants his female students to graduate safely uses a gentle and sweet whip.
