Is it better to exercise for 30 minutes at a heart rate that is in the "fat burn" zone or the "cardio" zone?

Hi Erin and to 3FC!

You will burn more calories by exercising at a higher intensity than you will at a lower intensity. If your goal is to create a calorie deficit through exercise, then yes, it's better to exercise at a higher intensity (the so-called cardio zone).

Check out our Top Ten Exercise Myths for more information about the myth of the fat-burning zone.
