Honestly I’ve seen some attitudes and articles that “housework isn’t exercise” and… I’m guessing such people don’t do much housework? At a minimum, it could often be a lot of walking, which is fine low to moderate exercise.
Have you ever found housework (or chores) to be good exercise?
Everything burns calories, even breathing. That doesn’t make it exercise. The only things on that list that could count are shoveling snow, moving furniture, and gardening, depending on what you are doing.
These kind of articles are dangerous and misleading. There is no amount of house work that is going to give you a healthy heart.
I have a dog and vacuum almost daily, it’s not exercise compared to taking him on a 2 mile walk that takes the same amount of time.
