I've been told here that my routine on an elliptical is not HIIT, but it's pretty good anyway. I basically use one of the pre-set interval programs, which alternate 2 minutes going hard with 2 minutes at an easy pace. Although I push myself as hard as I can for the 2 minute fast portions, I understand this is not HIIT because true sprinting could not be kept up so long.

Still, I find it difficult to do for 20-30 minutes, which is what I aim for (sandwiched around 15 minutes of steady pace). I am basically out of breath each time the fast portion ends and the heart rate is quite high.

I would switch to shorter interval periods, to imitate HIIT better, but I don't know how to customize the machines in that manner.
