This is really great! I was telling my fiancé about this workout just today. I read the NYT article but it was very sparse on details. Where can I find more info? About the research, more details about the workout itself (for example, during intervals is it full-on 100% all the effort I can muster, how many reps am I aiming for, is it done every day), etc?

Thanks for this. I'll give it a try in about an hour!
