If not, you should.
It's said to burn 9x more fat than steady state cardio. Yep, that means if you walk at a steady pace for 30 minutes, you'd burn 9 TIMES that if you were doing HIIT instead. More bang for your buck. More fun. And more effective. So why aren't you doing it? Don't know how? Don't know if it's for you?
You can do it by pushing your cardio to about 80% of your max for a minute or so, then taking another minute to 'cool down' a little bit. Then do it again. That easy. And it CAN be for you! Turbo Fire is my FAVORITE HIIT workout - it has lots of plyometric-style moves and Chalene is the best! It's a ton of fun. And for those folks who aren't ready to jump around and get crazy, there's always a modifier. You can follow her; her feet don't leave the ground, totally low-impact. If you want to try HIIT on your own, you can do it on a treadmill by alternating 1 minute sprints with 1 minute recovery jogs. This will give you a good idea of how it feels, but it can get boring. Cue Turbo Fire once that boredom sets in. But hey, that's just me. I look forward to the workouts and look better and feel better than I ever have...so I'm a true fan for life :)

Now go KILL that cardio and don't spend an hour every day on the treadmill when you could be getting MUCH better results from 15-20 minutes of HIIT!
