Physical exercise is obviously good for you, though.

Yes, and I enjoying swimming in the ocean for example. But I don't like swimming just for the sake of "it's good for you", don't know why and doesn't really matter.

Point is that some people know what's good for you, but cannot force them to do it just because it's good, we need something more :) Just because something feels like a "chore" doesn't mean you should avoid it.

This is an amazing little subthread here because in Book 2 of Plato's Republic Socrates lays out three classes of "good" in response to Glaucon. He categorizes physical training as the type "good only for their consequences" which he argues is not the highest form of good. Now, if one does genuinely enjoy the activity, he would elevate it to the highest form, which is "good both for their own sake and for their consequences".
