Apple recently added Cardio Fitness ratings, and… let's just say mine isn't good, albeit apparently improving slightly. The measurement is interesting, but not really actionable?

I'm guessing I'm supposed to do something like HIIT, which raises the question: in these pandemic days, what can I do that can be indoors in a relatively small apartment, so without the ability to have large gear nearby? Dumbbells?
