I'm thinking of trying something a bit different, I haven't done HIIT in a couple of years. I think I'm gonna try replacing my 30 minute moderate intensity elliptical sessions with 20 minutes of HIIT on the elliptical instead.
When I used to do it years ago on a treadmill I liked 2 and a half minute segments, 2 and a half of running, 2 and a half of walking, rinse and repeat.
I see that most people however like short 30 second intervals.
My elliptical I have at home is really nothing too impressive (hey it was 400 bucks on craigslist, lol) But can anybody give a good recommendation on a basic point to start at with intervals? 30 seconds all out, 30 seconds slow, for the entire 20 minutes?
