anyone else doing HIIT on the treadmill?

Just wondering if anybody does HIIT on the treadmill? I did my first 10 minute round of intervals plus 10 min warm up and cool down and it was crazy...my heart rate was soaring and i could barely stay on the treadmill. I was running at 7.0 for 30 seconds and then it took roughly two minutes of slow walking to get my heart rate down far enough before running another 30 seconds.. My legs burned!! I thought i wasnt going to make it through a 6 cycle interval session but i did- barely!! Thank God for a break day tommorow!

I love HIIT, I do it on the cross trainer and the treadmill.. Makes the time fly by. The other protocol I enjoy training with is tabata.. A 4 min set and you work for 20 secs, completely rest for 10 secs.. Works out at 8 rounds.. You can do this on the rower, cycling, plank and a whole lot of other things.. The idea is to really push yourself to max in those 20 secs. Keep running
