The reading I have done is it is a matter of getting your heart rate WAY up for two-three minutes, resting for one-two minutes and doing it again. From what I have read, and the routine I am going to pick up involving HIIT, the first week I'll be shooting to get a heart rate of 173 bpm during the high intensity portion (90% of my "max" heart rate for my age; which is 220 - your age). I CAN'T get my heart rate that high on a bike no matter how hard I try. I can barely reach it on an ellyptical. Running, just below an all out sprint gets me there in just a few seconds. I plan to buy a heartrate monitor when I do HIIT training.
To break it down even more. I plan the first week I do it, to do it 3 times a week, getting my heart rate up to 90% for two minutes at a time, with one-two minutes rest in between, and 4 high-intensity "sets" during the workout. I plan to warm-up for 5 minutes before, and cool-down for 5 minutes afterward. Total time doing it, 25 minutes. What I find funny are gyms who would be using it to get people in and out? It's something that you can do on your own without a gym membership? After the first week, the heart-rate target I'll go for is 95%, then up 5% each week, maxing out at 110% (it seems impossible to get your heart rate up that high, but supposedly after doing it for so many weeks it is possible to).
I'll let you know how it goes.
