Fat Burning Zone -VS- Cardio Training Zone
I often wonder which one is better. I always assumed cardio training was better because the heart rate is higher, but then always wondered why the other one is labeled FAT burning zone? I did a little research and this is what I found:

I found the article interesting and informative. Hope it helps you too.

Thanks!
