How to list multiple purposes for an action?

Question

So, one of the example sentences for ため that I see in the learning software I use is:

彼女はダイエットのために泳いでいる。

Which basically means, "She swims in order to lose weight."

But what if you wanted to say, "She swims in order to lose weight, and for fun?"

Answer 1

There's a common way of speaking to tell somebody does something with multiple purposes.

彼女はダイエットと趣味を兼【か】ねて水泳をしている。

兼ねる

_{Ichidan verb, Transitive verb}
2. to serve two or more functions or roles simultaneously; to contain (or combine) two or more features

Answer 2

You can use "と" like ダイエットと楽しみのために.
