Hello, I have a question. I wanted the sentences to have the same meaning as this sentence: "There is a reason why people should exercise more."

There is a reason for people('s) exercising more. I think it means people actually exercise more.
There is a reason for exercising more. ?? I'm not sure. I seems to me that it means the same thing as the two below.
There is (a) reason to exercise more.
There is (a) reason for people to exercise more.

Hello,

Please explain what you want the sentence to mean.

I want it to mean:
There is(exists) a reason(eventually reasons) why poeple(in general) should exercise more.
For example, to get in a better shape, to lose some weight, to get healthier, etc.

There is a reason for people to exercise more.

Thank you
I'd just want to ask one more question.

It's obvious the first sentence and the forth one mean different things, but I feel as if, because exercising doesn't have a subject in the second and third one and I've found many examples of both, they mean closely the same thing.

What do yuo think?

The 2d and 3d sentence say "there is a reason to do this", but for who? Is this a reason for pregnant women to do this? Is this a reason for short men to do this?

If you mean "for everybody" you need to say "for everybody" or "for people". It is not implied in sentences like 2 and 3.
