Meaning of 来锻炼 in the conversation

Question

What is the meaning of 来锻炼 in this conversation?

A: 老师，您每天都来锻炼吗？

B： 对，我每天都坚持锻炼。

I think the question means “Do you exercise daily?” But I do not know why “来” turns up and its meaning. Please make it clear.

Answer 1

In the sentence, 来 means "come". 来锻炼 means "come and do exercise"

So the question actually means: Do you come (here) and do exercise everyday?

Answer 2

So, any phrase "来 + Verb" means "come (here) and do something", right?

No, definitely not.

You can translate your sentence into English with:

老师，您每天都来锻炼吗？Teacher, do you come here every day to train?

But that is no guarantee that that is what the Chinese means.

It may just be: Teacher, you every day to train?

I see that kind of English a lot from Chinese students, which makes me think, that is what they really have in their heads. Chinese is not bound by English syntax rules.

These 3 sentences come from here.
