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
Your Maximum Heart Rate
The rate at which your heart is beating when it is working its hardest to meet your bodys oxygen needs is your maximum heart rate. Your maximum heart rate plays a major role in setting your aerobic capacitythe amount of oxygen you are able to consume. Several large observational studies have indicated that a high aerobic capacity is associated with a lower risk of heart attack and death. And a small controlled trial demonstrated that men and women with mild cognitive impairment who raised their aerobic capacity also improved their performance on tests of memory and reasoning.
How To Calculate Your Maximal Heart Rate
There is substantial variation in HRmax. The only true method of determining HRmax is to conduct a maximal exercise test. But HRmax can be estimated using formulas based on age.
The authors of a 2001 study proposed the following revised equation for estimating maximal heart rate:
HRMax = 208 –
This means a 45-year-old would have a predicted HRmax of 177 BPM.
Indeed, our genetics can influence actual maximal heart rates from their predicted value. However, HRmax is not a major determinant of exercise or athletic performance. Far more important is our physiological efficiency.
When assessing heart rate, its also important to take into account the effects of emotions such as excitement or fear, stimulants like caffeine, and circulating hormones like adrenaline, all of which can increase heart rate.

Keeping An Eye On Things
This is probably the easiest way to adjust your maximum heart rate reading, and will have good results over time. Its easy to do, because you just need to work out as usual. Take note of the intensity of your workouts. Look at the graphs and the heart rate data corresponding with your workouts. Were you pushing yourself to your absolute limits? If so, how does that correspond to the maximum heart rate percentage that the app is showing?
If youre seeing that your heart rate is much higher than your actual highest heart rate values when youre pushing yourself as hard as you can its a good idea to start lowering your maximum heart rate in the app. Similarly, if you ever see heart rate values above 100% its a good idea to raise your heart rate in app to correspond with your new maximum heart rate.
Help Your Heart Work Stronger
Cardiovascular exercise is especially effective in keeping your heart healthy and reaching your target heart rate. This specific type of exercise gets your heart beating fast for several minutes at a time.
Target heart rate is defined as the minimum number of heartbeats in a given amount of time in order to reach the level of exertion necessary for cardiovascular fitness, specific to a persons age, gender, or physical fitness.
The following is an estimate given by the American Heart Association for target heart rate numbers for adults ages 45 to 70:
- 45 years: 88 to 149 beats per minute
- 50 years: 85 to 145 beats per minute
- 55 years: 83 to 140 beats per minute
- 60 years: 80 to 136 beats per minute
- 65 years: 78 to 132 beats per minute
- 70 years: 75 to 128 beats per minute

Exercise Makes Your Heart More Efficient
Typical resting heart rate can vary quite substantially between people and even within an individual. Around 60-80 beats per minute for adults is common.
Heart rate can be easily be measured with devices like FitBits and Apple Watches, although they have their limitations.
Improving your aerobic fitness reduces your resting heart rate, as the heart becomes more efficient with each beat. An athletes resting heart rate, for instance, is typically around 40 BPM.
In fact, evidence suggests that long-term exercise training increases the size of the heart, specifically the left ventricle, a phenomenon known as Athletes Heart. A bigger heart means more blood can be pumped with each beat, and fewer beats per minute are required to maintain blood flow around the body. This is a beneficial physiological adaptation allowing athletes to exercise at higher intensities for longer.

If you have any heart problems, are on any medication, or have been advised by your doctor to stay within a certain bpm range, make sure you follow their instructions. And, as always, check with your doctor before starting any new fitness regimen.
Target Heart Rate Zone Calculation Methods
- Basic by Age
- This is historically the most common calculation and used by the American Heart Association. THR is calculated by multiplying percent intensity by the MHR. Example: At 70% intensity THR = MHR x 0.70.
- Karvonen by Age & RHR
- This method calculates THR using the Karvonen Equation. MHR is calculated using age and allows you to enter a measured RHR. Example: At 70% intensity THR = x 0.70) + RHR.
- Karvonen by MHR & RHR
- This method calculates THR using the Karvonen Equation and allows you to enter both a measured MHR and a measured RHR. Example: At 50% intensity THR = x 0.50) + RHR. Where MHR – RHR is called your Heart Rate Reserve .
TheAmerican Heart Association recommends target heart rate zones for exercise at 50% to 85% intensity of MHR and defines a heart rate during moderately intense activities at 50-70% of MHR, and heart rate during hard physical activity at 70-90% of MHR.

Heart Rate Reserve Example
How to calculate heart rate reserve?
Using the calculator linked above, determine your maximum heart rate based on your age and gender.
Subtract your resting heart rate from your maximum heart rate to determine your HRR.
Use The Heart Rate Reserve Formula
While not technically a measure of max heart rate, another formula you can use to determine training intensity is the Karvonen method, or heart rate reserve formula. Your heart rate reserve is a measure of the difference between your maximum heart rate and your;resting heart rate; in other words, the range of speeds at which your heart is capable of contracting. Since HRR factors in your resting heart rate a loose measure of your current level of cardiovascular fitness its a good one to use if youre training consistently and seeking higher levels of cardiovascular fitness.
To calculate training intensity using HRR, follow these steps:
First, measure your resting heart rate:
- Gently place your fingertips on one side of your windpipe until you find a pulse.
- Count your heartbeats for 30 seconds and multiply the result by 2 to calculate beats per minute .
- For a more accurate reading, measure your RHR first thing in the morning, before getting out of bed.
Second, find your heart rate reserve:
- Subtract your RHR from your MHR. Men should use the Inbar formula for this; women can use either Inbar or the Gulati formula .
So, a 30-year-old man with a resting heart rate of 60 BPM would subtract his age x 0.685 from 205.8 to get an MHR of 185, then subtract his resting heart rate to get 125.
Third, determine your exercise intensity:

How Do Heart Rates Affect Workouts
Heart rate zones let you know how hard your heart is working and what energy source youre using carbohydrates or fat. The higher your heart rate gets, the more youre relying on glycogen from carbohydrates for fuel.
For endurance athletes, its best to exercise in the zones that mostly rely on fat for fuel, says Travers. Fat is a longer-lasting energy source and better for longer, intense workouts.
Best heart rate zone for fat loss
Youll burn fat at every exercise heart rate zone. If youre just starting to exercise, aim for the lower-intensity heart rate zone. As you build stamina, push yourself into the next zone until youre comfortably at the aerobic level. Thats your heart getting stronger.
Cardio exercise is designed primarily to improve heart and metabolic health, says Travers. It helps lower your:
- Blood pressure.
- Blood sugar.
For fat loss, he recommends strength training to build muscle. Having more muscle mass boosts your metabolic rate , helping you burn more calories throughout the day.;
If you havent been active before, then cardiovascular exercise will help with weight loss in the beginning. But at some point, youll become aerobically fit, Travers notes. Then you wont use as much energy to complete the same amount of exercise, so youll stop seeing significant weight loss.
What Are Exercise Heart Rate Zones
Heart rate zones are a percentage of your maximum heart rate . Exercise too close to your maximum HR and your heart and body will struggle to keep up with the demands.;
The goal of heart rate zones is to make you the most efficient, but to allow you to challenge yourself to improve cardiovascular fitness, says Travers.;;
Exercise heart rate zones are the training levels based on your maximum heart rate.;As you increase your pace, cadence and workload, you increase the demands on your heart. Travers breaks it down:;
- Lower-intensity zone:;Youre exercising at 50% to 60% of your max heart rate. At this point, 85% of the calories you burn are fat. The downside? Youre burning fewer calories overall than you would if you were exercising at a higher intensity. Youre generally able to sustain this zone the longest amount of time.
- Temperate zone:;Youre exercising at 60% to 70% of your max heart rate. Roughly 65% of the calories you burn are fat.
- Aerobic zone:;Working at 70% to 80% of your max heart rate puts you in the aerobic zone. About 45% of the calories you burn are fat. But youre burning a higher number of overall calories compared to the other heart rate zones. You generally sustain this zone the shortest amount of time.;

Target Heart Rate And Estimated Maximum Heart Rate
For moderate-intensity physical activity, your target heart rate should be between 64% and 76%1,2 of your maximum heart rate. You can estimate your maximum heart rate based on your age. To estimate your maximum age-related heart rate, subtract your age from 220. For example, for a 50-year-old person, the estimated maximum age-related heart rate would be calculated as 220 50 years = 170 beats per minute . The 64% and 76% levels would be:
- 64% level: 170 x 0.64 = 109 bpm, and
- 76% level: 170 x 0.76 = 129 bpm
This shows that moderate-intensity physical activity for a 50-year-old person will require that the heart rate remains between 109 and 129 bpm during physical activity.
For vigorous-intensity physical activity, your target heart rate should be between 77% and 93%1,2 of your maximum heart rate. To figure out this range, follow the same formula used above, except change 64 and 76% to 77 and 93%. For example, for a 35-year-old person, the estimated maximum age-related heart rate would be calculated as 220 35 years = 185 beats per minute . The 77% and 93% levels would be:
- 77% level: 185 x 0.77 = 142 bpm, and
- 93% level: 185 x 0.93 = 172 bpm
Important To Get The Maximum Heart Rate Right
Maximum heart rate is an important tool to uncover cardiovascular disease. During stress testing, age-expected maximum heart rate is used as a guideline for when the test should be concluded. If the test is finished before the load is high enough, you risk not to detect subclinical heart disease.;Therefore, it is of great clinical relevance to have a way to;accurately estimate;HRmax.
The traditional formula for determining HRmax is “220 minus age”, but;can underestimate HRmax by up to 40 beats per minute in seniors. In fact, the method is inaccurate already at an age of 3040 years, and gets;more inaccurate the older you are.
In The HUNT Fitness Study, we measured accurate maximum heart rate in 3,320 healthy adults aged between 19 and 89. Based on these tests we made a completely new formula which estimates maximum heart rate far more accurately than “220 minus age”. The HRmax Calculator is based on this formula: “211 – 0.64*age”.

Easy Steps To Find Your Target Heart Rate Range
Ryan Lawson, Exercise Specialist
Were all familiar with the phrase use it or lose it, and it perfectly applies to our body and muscles. Muscles are made to be used, and if theyre neglected its our health and quality of life that suffers.
Cardiovascular exercise is defined as any activity that increases your heart rate. Elevating your heart rate for an extended period of time will improve your heart health. A stronger, healthier heart is able to more efficiently deliver oxygen to the muscles and also burn more fat while youre exercising and resting.
The benefits of a stronger heart through cardiovascular exercise are numerous. In addition to a stronger heart and lungs, regular exercise has been shown to lead to better sleep, less stress, reduction in mood swings and depression and an overall more active lifestyle.
You have a target heart rate zone that you should strive for during activity. A simple way to calculate it would be to first find your predicted maximum heart rate, which you can find by subtracting your age from 220. Once youve figured your maximum heart rate, you can find your target healthy heart rate range by multiplying your maximum heart rate by 65 percent to find the low end of that range and multiply your maximum heart rate by 85 percent to find the high end of the range.
Example: The maximum heart rate for a 45-year-old is 175 and the target heart rate range would be about 113 to 149 beats per minute.
