Is this a set phrase: "best of all"?

[Torsten]

"Best of all" does doesn't mean "first of all". It means, that it's the most favourite out of all the rest. The phrase "next of all" simply doesn't exist in English so nobody would use it.

Hi,

'Next of all' is not a grammatically correct expression at all. It doesn't mean secondly.

Oh, yes.....
I see.

Thanks!!!

I chose "before of all" because I think if the answer is "best" it will have "the".
Now, I see other choice.
Thank you so much

Hi
Your explanation is completely right. But please let me know if I can use this sentence "what exercise do you like next to all".
It is because we must use "to" after next and it means that after doing all of your exercises, what kind of another exercise do you like. Is it true?

No, that sentence is not correct.

'What exercise do you like best of all?' is the correct expression.

Hi,

Why when we use "best of all" we don't say "the best of all". Or we only say "What exercise do you like doing the best?" ? And How to use "the most favorite" in this sentence?

Thanks.

[Beeesneees]

You can add the 'the' is you wish. It will still be correct and won't make any significant difference, though would provide a slight indication that you are making a choice from a more limited range of options (best of all the ones that are being spoken about).

"Which exercise is your favourite one?" or "Which is your favourite exercise?" (You can add 'most' before favourite in both of those if you wish, though they are most commonly written without, as I have here.)
