that's not how i understand the term "high intensity." jogging makes me pant, but i wouldn't call it high intensity, because i can do it for twenty minutes.

high intensity would be work you can do for only maybe a minute, not twenty, and as a result it won't keep your heart rate elevated very long.

so if they're basically saying 30 minutes 5 days a week, that's low intensity exercise.

Actually according to the article, high intensity can be done for twenty minutes. So what you’re calling “low intensity” is actually “high intensity.”

(Funny how this works both directions, isn’t it?)

Low intensity shouldn't involve panting at all, because low intensity exercises are designed for people with specific health issues where anything above slight exercise is dangerous to them. [consider: significant osteoperosis, serious heart disease, etc] Stretching is low intensity exercise.

Also, an exercise you can only keep up for 20 minutes at a time is pretty high intensity.
