As a general rule, adults will have a resting heart rate of 60 to 100 beats per minute (bpm). In general, people with better physical fitness will have slower heart rates than pepole who exercise less. Athletes, for instance, may have a resting heart rate of just 40 to 60 bpm.

If your heart rate exceeds 185 beats per minute during exercise, it is dangerous for you. Your target heart rate zone is the range of heart rate that you should aim for if you want to become physically fit. It is calculated as 60 to 80 percent of your maximum heart rate.

For most adults, a resting heart rate of 50 to 100 beats per minute is considered normal. People who exercise regularly often have lower resting heart rates. In some situations, such as periods of acute stress or danger, blood pressure and heart rate may both increase at the same time, but that's not always the case.

During exercise, heart rate can rise dramatically, from a resting rate of 60–80 beats per minute to a maximum rate of about 200 for a young adult. While you are running, blood flow is diverted toward tissues that need it most. For example, muscles in the arteries in your legs relax to allow more blood flow.

Now multiply 95 by 0.85 (85%) to get 80.75, then add your resting heart rate of 80 to get 160.75. Your target heart rate zone for vigorous exercise is 146.5 to 160.75 beats per minute.

Once exercise begins, the sympathetic nervous system is activated and the heart rate rises quickly. Heart rate also rises by simply thinking about exercise, which is referred to as anticipatory heart rate response. The parasympathetic division helps to slow down heart rate and respiration.

Exercise makes your heart more efficient Around 60-80 beats per minute (BPM) for adults is common. Improving your aerobic fitness reduces your resting heart rate, as the heart becomes more efficient with each beat. An athlete's resting heart rate, for instance, is typically around 40 BPM.
