The new formula for women, based on the new research, is 206 minus 88 percent of age. At age 50, the original formula gives a peak rate of 170 beats per minute for men and women. The new women's formula gives a maximum heart rate of 162 beats for women. Many men and women use their peak heart rate multiplied by 65 to 85 percent to determine their upper heart rate when exercising.
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.
