Short intervals of intensity best for fat burning, an Australian study says

Here's a tip for making the most out of your workouts that I learned from Fitsugar: Get your heart rate up with an 8-second interval of high-intensity, and follow it with 12 seconds of moderate intensity. Do this for 20 minutes and you'll burn more fat than you would working out as you normally would. This is basic interval training, but it's training in very short bursts, which is sure to keep you from getting bored.

Still skeptical as to how well this can work in burning fat? Read the studies that back this up.

What do you think of interval training? It's effective but I think it's hard to get used to if you're a runner who likes a steady speed.
