I've been doing HIIT for a week now but I sprint for 40 seconds instead of 20.
It just kills your legs. I actually just did it this morning. Walking stairs is a workout in itself right now.
It's great though because it only takes about 20 mins so I have time to get a very good workout in between classes.
