Yes they are. I was using "HIIT" improperly. Henceforth and evermore, I shall refrain from using "HIIT" improperly, because I have seen the light; although I might not give a sh**, others do.
What I do is set the speed on the stair machine at a baseline pace that puts my heart rate in the 150's, by itself. I do 30-second intervals at 50% higher speed, and that will get my bpm up to the mid 170s; then back to the baseline pace for 90 seconds and my bpm will drop down to 160 or so. That's about as intense as I care to do for 30 minutes, without taking a break.
While we're on the subject of each others' workouts, tell me about the 02 trainer, what benefits do you get from that?
