Best cardio pace and time

What is the best cardio speed and time for fat loss?

HIIT for 15-30 mins seems to have the greatest effect in studies on 24 hour calorie expenditure
 
depends on who u ask and how much time u have

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.
