"Please do not stop walking every day."

Translation: 毎日さんぽするのをやめないでください。

Why の after する?

[Untitled_Name]

の is a verb normalizer. Unlike in English, Japanese can't use a verb (する here) as a subject or object to another verb (やめでください here). That's why の is used. の turns the first part of the sentence (walking every day) into a noun, so it can be used as a direct object.

こと「事」 is another verb normalizer (which means 'thing'), so using こと here would make the sentence literally: "Please do not stop the (walking every day) thing".

For extra information, any noun can be used here. So for example: しりません人 (a don't know person) would mean: "a person (I) don't know". This is different to 人をしりません, which means "(I) don't know the person."

Why さんぽする instead of 歩く？

[R0dluvan]

I guess because "aruku" would imply only walking any amount (which everybody does unless they're physically disabled or injured) whereas "sanpo suru" implies a whole Walk, outdoors, which the English sentence probably entails (though it's not unambiguous).

[HunBug]

In an another example it was said that する+の was unnecessary, because するturns the noun to verb then の turns it back to noun. Why we need this here?

Why is there no particle connecting sanpo and suru?

[MargauxMcD]

I guess it's like "renshyu suru" Renshyu is practice when on its own where as when it's with suru it becomes the verb "to practise". Sanpo suru becomes "to take a walk".

I'm interested in why 「のを」was used instead of 「のが」, which is more familiar to me.

[0NEB3]

やめる is transitive and takes an object naming the thing that is being quit (in this case, the walks). If you used the subject particle が instead of を, it would mean the walks themselves were quitting something.

Is する absolutely necessary here?
