^^^^Yeah. Read the sticky like JC said. I posted another article in the articles section which is linked at the end of that.

Then see what you think.
One possible advantage to HIIT that I don't think many people consider is, instead of just lack of catabolism, anabolism. Think about the fact that you need a glycogen rich environment to grow muscle. This means a WHOLE lot of carbs for many of us. Which could also mean some fat. But high intensity cardio gives you the same window of oppurtunity as your weight training to increase you glycogen levels quickly because of the insulin sensitivity.
I.E., you follow your HIIT with a post workout regimen the same as with your weight work so that you muscles are sucking up nutrients while you are enjoying greater post exercise fat burning.
