no you cannot program intervals. I assume you know that there's no resistance levels on an airdyne- the resistance is equal to how hard you push.
now, the screen displays 5 different things- time, calories burned, rpm, distance...and maybe mph?- I have the ad2, other models may display more/less. it automatically switches between these, spending 5 seconds on each before going to the next; I feel like my wording was a little weird- it will show your time for 5 seconds, then calories burned for 5 seconds, then the next for 5...etc. SO- as long as you're a little less dumb than average, you can use these 5 second display intervals to time your sprint intervals.
*as I sit here thinking about it, it takes 30 seconds to make a full revolution of the display, so if you start at 00:00, by the time it goes through the rest and gets back to the time, it's showing 00:30, so maybe there's 6 things displayed? anyway, you can easily use it to time sprints.
