A healthy fitness zone is a range of health numbers for your particular weight and height. An example of a healthy fitness zone is exercising at 50-60% of your maximum heart rate.
the average heart rate for a child (Children) is 95 beats in a minute. The range of normal is 70 to 110. this is the pulse of a healthy child's heart.
