Exercise keeps me in good shape : Is this sentence correct?

Question

I've seen this two sentences im my country's English dictionary.

I exercise every morning to keep myself in good shape.

---

It's important for him to keep in good shape.

So i became curious if i can use the sentence below :

Exercise keeps me in good shape.

Or, should I write the sentence like this? :

Exercise helps me keep in good shape.

Answer 1

"Exercise keeps me in good shape." would be understood by any native English speaker to mean that you exercise to keep your body fit.
