I know that ~てやる is to do something for someone.

I also know that やるもんじゃない means "shouldn't do"

I have a feeling I should ignore ~てやる because て is a part of つけて.

However, I don't know what つけて is supposed to mean after 助走

Anyway, for context, I'm reading about a guy asking a girl to stretch. He
says:

> じゃあ背中押してもらえるかな
>
> 助走つけてやるもんじゃないから柔軟は
>
> 体硬くてごめんね

I'm mostly confused what つけて's role is and how the rest of やるもんじゃない combines
with it.

Not to mention the word 助走 doesn't seem to have a good translation to English?

I'm having a tough time deconstructing the meaning behind all the parts

question
grammar
meaning of つけて in 助走つけてやるもんじゃない
助走つける take a run up

助走つけてやるもの something you take a run up for

助走つけてやるもんじゃない not something you need to take a run up for

つける means to “add” the run up for whatever it is you’re taking the run up for

In this case it seems to be that he’s asking someone to help stretch by
pushing his back. They put too much effort in so he says “you don’t need a run
up for stretching”

Look on YouTube for examples of 助走

answer
助走 literally means a run-up or a running start in sports. 助走をつける is a more or
less fixed collocation. I think the use of the verb つける is influenced by
勢いをつける. In its figurative sense 助走をつける is practically interchangeable with
勢いをつける, meaning to get a momentum before you do something.

やる is a colloquial version of する, not of あげる, in this context.

Your sentence would be translated to something like:

> Stretching (or helping someone do it) is not something you do with a running
> start, you know.

If the girl said this, she must have thought the guy was asking her to push
his back forcefully and reminded him that that's not how he should be
stretching his body.
