layne norton likes hiit because it will continue to burn fat....he says low intensity will also burn fat but in a short period of time will become less effective
i also like the idea of hiit training if you don't want to spend all day in the gym doing cardio
however i know people who swear by low intensity cardio, they say doing something like walking at an incline allows them to burn fat while maintaining muscle and not burning it off
HIIT builds fitness faster. 30 min @ 60% vs 10x4 @ 90% w/ 2 min rest. Aerobic capacity increased by 13%, fat burning capacity up by 36%, and key aerobic enzymes increased by 25%

High intensity weight training boosts blood sugar control.
Strength training increases fat metabolism by stimulating beta-adrenic receptors – cell structures that make adrenaline and increase metabolism and fat use.
Improves blood sugar metabolism
Univ. of Montana, led by Andy Miller showed that high intensity/low volume weight training promoted better blood sugar regulation than low intensity/high volume work.
i used to run a few miles every day as a newb and with my tall frame I just lost mass all over. It was a big waste of time.
HIIT is far superior to long cardio sessions if you want to burn fat and keep muscle. It made a HUGE difference and I'll never go back. I get done in 1/3 of the time now too. Sprinting uphill in intervals is king.
