This is my normal routine on the treadmill,3 days a week for 30 minutes. Just recently started reading about HIIT, would this routine be considered as HIIT??

3 minutes of fast walking to warm up
2 minutes of jogging
5 minutes of 30 seconds all out sprint and 30 seconds of jogging
1 1/2 minute of walking brisk
5 minutes of 30 seconds all out sprint and 30 seconds of jogging
1 1/2 minute of walking brisk
5 minutes of 30 seconds all out sprint and 30 seconds of jogging
1 1/2 minute of walking brisk
2 minutes jogging
1 minute all out sprint
2 minutes slow walk
stretching

when walking my heart rate is 60-70%
jogging its at 75%
sprinting its about 85-90%

thanks for any input/advice?

That looks great! Try changing the incline too to make it more interesting
