Heart rate zone training is always useful for general health. Unless you have an ultra terminal illness you would probably benefit from some zone 2 training...basically just a brisk walk(where you can still have a conversation, but you feel like you're putting in more work than sitting on a couch, probably around 125 bpm) for 45 mins 2 or 3x a week will greatly improve the heart health for most people.

I no longer do HIIT of any type, but do frequently leave my couch and indeed my home. I wear a smartwatch that reads pretty close to my real heart rate and is, if not ideally accurate, then at least sufficiently precise. More than that these days would be wasted on me. But I appreciate your motivation in commenting, and confide many here might benefit by your good effort.
