What is the "fat burning zone"?

Answer by  zk33 (12)

The fat burning zone is an age-dependent heart rate interval that is thought to maximize fat loss percentage when exercising. That is you may loose more calories in total if your heart rate is higher, but in this zone, you mostly loose fat. It is about 65 to 80% of your max heart rate.

"Fat burning zone" is a term used on equipment for cardiovascular workouts. It means your heart rate is higher than for warmup, but not as high as for cardio.
