I've found that even when machines have interval options, their intervals tend to be too long.
Yea, they had it at my old gym. It was nice as you just hit a button and it would switch between your two speeds.
It seemed to be smoother as I didn't have to hold the speed down button.
Anyways, you can really do HIIT with anything. I do it while working out my legs every other week.
