For most adults, normal heart rate is 60 to 80 BPM. Well-trained athletes can have a normal heart rate of 40 to 60 BPM. When you work out, your heart rate will get higher. This is called your active heart rate. Active heart rates, like resting heart rates, differ in people and change as you age. Generally, a healthy active heart rate is 60 to 80 percent of your maximum heart rate, or the highest your heart rate should safely go.
