Why It’s Important To Know Your Mhr
Maximum heart rates can vary from person to person and they are not an indicator of physical fitness. In other words, it doesn’t rise as you get stronger or faster, and it doesn’t mean that someone with a higher MHR is in better shape than you.
However, knowing your max HR can help you track your fitness progress and determine your target heart rate. That can give you a more exact method of determining your exercise intensity than using your perceived exertion.
Here are a few examples:
- Low intensity: 40% to 50% MHR
- Moderate intensity/healthy heart zone: 50% to 60% MHR
- High intensity/fat-burning zone: 60% to 70% MHR
- Max intensity: 85% to 100% MHR
Getting Older Affects Your Max Heart Rate
The other day I went for a run with my son. Were good training partners: If we raced a 5K today wed finish within less than a minute of each other. I know that wont be the case for long, but these days, when we head out on an easy run, our effort level is roughly the same for the same pace.
At that easy pace, however, his Fitbit tracker shows his heart rate hovering around 175 beats per minute, while mine stays in the low 130s. Even if I started sprinting all out up a hill I wouldnt be able to raise my heart rate to the beats per minute that he hits as soon as he starts working hard. Lately, I max out in the high 160s.
Am I just in better shape than he is? Nope. Its more likely due to the fact that Im 52 years old and hes 15.

If You Slow Your Resting Heart Rate Can You Slow Down Aging
Having a lower resting heart rate is associated with having a longer lifespan.
Athletes generally have a lower resting heart rate due to their physical fitness.
One study found that the more physically fit you are, the lower the resting pulse. The same study found that even controlling for physical fitness, people with a higher resting heart rate had a shorter life expectancy compared to those with a lower resting heart rate.
So a high resting heart rate is not just a marker of risk, but a risk factor for premature death. The difference between a risk marker and a risk factor is that if you can control the risk factor, you can control the risk.
Why Is A High Resting Heart Rate Dangerous?
If your heart is beating fast 24 hours a day, all that circulatory stress can damage the elastic fibers supporting your arterial walls causing them to become stiff. Your arteries do not have enough time to relax between beats.
Maximum Heart Rate And Exercise
During 4×4 interval training, you use your maximum heart rate to give the heart good exercise. Our HRmax Calculator calculates at which heart rate you should exercise when performing this kind of interval training. The 4×4 principle can be used in a variety of activites, including running, biking, swimming and rowing.
Watch our video for further explanation on how to perform effective 4×4 interval training:

What You Can Do
You should always aim to take good care of your heart. This includes doing things like exercising regularly, eating a heart-healthy diet, and maintaining a healthy weight.
Additionally, you should plan to visit your doctor regularly for physicals. Not only is it good practice, but it can also help with early detection of things like high cholesterol or blood pressure abnormalities.
If you already have heart disease, you should carefully monitor your condition and stick to your treatment plan. Take all medications as instructed by your doctor. Be sure to promptly report any new or worsening symptoms.
Some additional preventative health tips to help keep your heart healthy and happy include:
- Find ways to reduce stress. Examples of ways to do this can include things like yoga or meditation.
- Limit your caffeine intake. Using too much caffeine can lead to increases in heart rate.
- Moderate your drinking. Women and men over 65 should only have one drink per day. Men under 65 should only have two drinks per day.
- Quit smoking. Smoking increases your heart rate and quitting can help bring it back down.
- Be aware of medication side effects. Some medications can affect your heart rate. Always be aware of possible side effects before taking a medication.
Your heart is a muscular organ that works to pump oxygen-rich blood and nutrients to the tissues of your body. The muscles of your heart contract and relax to push blood through your blood vessels.
How To Measure Heart Rate
The most convenient places to measure your heart rate are on the wrists or one side of the neck. For an accurate reading, put two fingers over one of these areas and count the variety of beats in 60 seconds. You can also do this for 20 seconds and increase by 3, which might be easier, Bauman stated. Using your thumb may be confusing since sometimes you can feel a pulse in the thumb, she said.

What Is A Normal Heart Rate
A normal resting heart rate is usually between 60 and 100 beats per minute. Your number may vary. Children tend to have higher resting heart rates than adults.
The best time to measure your resting heart rate is just after you wake up in the morning, before you start moving around or have any caffeine.
Correlation With Cardiovascular Mortality Risk

A number of investigations indicate that faster resting heart rate has emerged as a new risk factor for mortality in homeothermic mammals, particularly cardiovascular mortality in human beings. Faster heart rate may accompany increased production of inflammation molecules and increased production of reactive oxygen species in cardiovascular system, in addition to increased mechanical stress to the heart. There is a correlation between increased resting rate and cardiovascular risk. This is not seen to be “using an allotment of heart beats” but rather an increased risk to the system from the increased rate.
Given these data, heart rate should be considered in the assessment of cardiovascular risk, even in apparently healthy individuals. Heart rate has many advantages as a clinical parameter: It is inexpensive and quick to measure and is easily understandable. Although the accepted limits of heart rate are between 60 and 100 beats per minute, this was based for convenience on the scale of the squares on electrocardiogram paper a better definition of normal sinus heart rate may be between 50 and 90 beats per minute.

Medical Tests For Heart Disease
Your doctor will check your blood pressure and do a fasting blood test to check your cholesterol, a type of fatty substance that can contribute to plaques in your arteries. He or she might also do a blood test to check the levels of proteins that are markers of inflammation in the body and suggest you have an electrocardiogram . This test looks at electrical activity in your heart. A chest x-ray will show whether your heart is enlarged or your lungs have fluid in them both can be signs of heart failure. The doctor might do a blood test for brain natriuretic peptide , a hormone that increases in heart failure. If the cardiologist needs to determine your heart or valve function, he or she may order an echocardiogram, a painless test which uses sound waves to produce images of your heart in motion.
To learn more about heart disease, visit the National Heart, Lung, and Blood Institute.
Your Target Heart Rate Is What Matters
One way you can compensate for a slower heart rate is to get and stay fit. The Centers for Disease Control and Prevention recommend that adults get 150 minutes of moderate-intensity cardio a week or 75 minutes of vigorous-intensity aerobic activity a week.
When you go into serious training, you stretch the cardiac muscles, says Benson. Thats how you improve stroke volume. And, according to the American Heart Association, when your stroke volume is highermeaning your body can pump more blood with each heartbeatthe heart doesnt have to beat as many times to deliver the same amount of blood to your muscles.
So how can you try to exercise at the right intensity? If you own a Fitbit Alta HR, Charge 2, Blaze, or Surge and have your birthday logged in your profile, your tracker can help. Heres how it works: Using the common formula of 220 minus your age, Fitbit will calculate your maximum heart rate and then create three target heart rate zonesfat burn , cardio , and peak based off that number. After exercising, you can click on the workout summary within your exercise tile to see how many minutes you logged in each zone.
These zones explain why my son and I can run togetherat different heart ratesand feel like were expending the same amount of effort.
For instance, at age 15, my sons max heart rate is 205 and his cardio heart rate zone is 144 to 172

What Is Your Heart Rate
Your heart rate, or pulse, is the number of times your heart beats in 1 minute. Heart rates vary from person to person. Itâs lower when youâre at rest and higher when you exercise.
Knowing how to find your pulse can help you figure out your best exercise program. If youâre taking heart medications, recording your pulse daily and reporting the results to your doctor can help them learn whether your treatment is working.
Blood pressure vs. heart rate
Your heart rate is separate from your blood pressure. Thatâs the force of your blood against the walls of your blood vessels.
A faster pulse doesnât necessarily mean higher blood pressure. When your heart speeds up, like when you exercise, your blood vessels should expand to let more blood pass through.

Understanding A Normal Heart Rate In Your Age
Your heart is a muscle and similar to enhancing other muscles by doing activities, you can do the exact same thing with your heart, said Dr. Mary Ann Bauman, an internist at Integris Baptist Medical Center in Oklahoma City.
Understanding about your heart rate can help you monitor your physical fitness level, and it might assist you spot establishing illness if you are experiencing other symptoms.
If you are an athlete and youre training, or if you are having symptoms such as dizziness, then understanding your heart rate is important, Bauman said. However as a general guideline, unless someone is having issues, its not extremely important to constantly understand what your heart rate is.
What Happens If I Go Over My 90% Heart Rate Goal When I Exercise
One of the reasons that experts recommend that you see your doctor before you start any exercise program is so that you can determine just how much exercise you can do. It doesnt matter how out of shape you are you have to find exercises that are safe for you to participate in.
If your heart rate exceeds your 90% max, then you need to slow down. You dont necessarily have to stop unless slowing down doesnt help your heart rate to decrease. If you exceed your maximum heart rate, then you may need to seek medical attention, especially if you exceed it by large amounts.
As time goes on, you will find that as you get stronger it will take more work for you to get your heart rate to go up as high as you want it. That is the benefit of being a healthy person.
The good news is that, once you meet your weight loss or health goals, then you wont have to worry about getting your maximum 90%. Instead, you will simply want to work toward maintenance, which doesnt require such intense exercise.
Do yourself a favor and invest in a heart monitor that you wear on your wrist so that you can keep track of your heart rate. This will ensure that you meet your goals and dont exceed your maximum safe heart rate at the same time.

Average Resting Heart Rate By Age
Keep in mind, your heart rate during exercise is unique to you and only tells you how hard you’re working – not how fit you are. Therefore it isn’t accurate to compare heart rates between two different people. Besides having different target heart rates by age, your average resting heart rate will also differ. For adults 18 years old and older, a normal resting heart rate is between 60 and 100 beats per minute . Keep in mind this does depend on the persons physical condition and age though. For children ages 6 to 15, the normal resting heart rate is between 70 and 100 bpm. A good time to check this is in the morning after youve had a good nights sleep, and before you eat or drink anything. When it comes to resting heart rate, lower is better because it means your heart muscle is in better condition and doesnt have to work as hard to maintain a steady beat. That’s why an athlete or more active person may have a resting heart rate as low as 40 beats per minute. If your heart rate is higher or lower than average and you don’t exercise regularly, be sure to see a doctor to see if it’s another underlying issue.
