High Intensity Interval Training
There's a lot of information in the internet about it. Basically, it's a short workout where you cycle between brief periods of high intensity and low intensity.
There's lots of ways to go about it. Personally, I usually just do 30 seconds of sprinting followed by 30 seconds of slow jogging for 8-10 minutes.
HIIT is meant to kick your ass, speed up your metabolism and get you into good shape quick. The best part is that there isn't much time required to get a good workout from it.
Obviously, balance is needed in any exercise routine, but I'd definitely recommend mixing in HIIT a few times a week. I do it on days I have lots of classes and don't really have the time to allocate toward a 60-90 minute workout.
There's a lot of biochemistry behind it that I don't feel like getting into, but as I said there's lots of good information out there on the internet about it.
