Unless you're actively consuming something like watching tv or reading a book while you do it.

When it comes to more passive consumption like listening to music while you exercise for background noise, I would still argue it's at least neutral. But if you're listening to an audiobook or podcast (something new to you), then it feels consumption again.

It depends. If you're trying to get to a particular shape, it could be seen as creation - getting creative with your body. But if it's just maintenance exercise, than this IMO belongs to the third category of things - it's a chore. A maintenance task. The work you have to do to stand still. Something that I personally strive to minimize.
