Factors That Affect Mhr
While most formulas calculate a ballpark MHR based on your age and gender, it’s actually more complicated than that. All of these factors can come into play in determining your MHR:
- Age: Your MHR can decline as you age.
- Altitude: Altitude can lower your MHR.
- Fitness: MHR has nothing to do with how physically fit you are.
- Genes: Your MHR is influenced by your genes.
- Individual differences: MHR can vary significantly even among people of the same age and sex.
- Size: MHR is usually higher in smaller people, which is why women often have a higher MHR than men.
- Working out: Training doesn’t really change your MHR, but if there is any change, it may get lower as your body experiences expanded blood and heart volumes.
Calculate Your Maximum Heart Rate
The easiest way to do this is a simple paper-and-pencil calculation. Subtract your age from 220. The result is an age-predicted maximum beats per minute.
It’s important to note that this method does not take into account your fitness level or inherited genes, which can make your true maximum heart rate 10 to 20 beats per minute higher or lower than the age-predicted number.
A second method to calculate your maximum heart rate is to have an exercise tolerance or stress test. This usually is supervised by a physician and performed in a hospital or clinical setting in three-minute stages, during which the speed and incline continue to increase in an effort to elevate your heart rate until it climbs to its highest level.
How To Calculate Your Training Heart Rate Zones
Heart-rate training benefits everyone, from the beginning exerciser trying to lose weight, to individuals trying to improve their cardiovascular fitness, to the highly conditioned athlete preparing for the next competition.
The key to making progress is to elevate your heart rate into the correct training zone, so your effort matches your goals.
Here are seven easy-to-follow steps that will help you calculate your ideal heart-rate training zone.

How To Find Your Target Heart Rate
First, it helps to know your resting heart rate, Martin says. Find your pulse . Then count the number of beats in a minutethats your resting heart rate. The average resting heart rate is between 60 and 100, he says. The more fit you are, the lower your resting heart rate for very fit people, its in the range of 40 to 50 beats per minute.
Target heart rate is generally expressed as a percentage of your maximum safe heart rate. The maximum rate is based on your age, as subtracted from 220. So for a 50-year-old, maximum heart rate is 220 minus 50, or 170 beats per minute. At a 50 percent exertion level, your target would be 50 percent of that maximum, or 85 beats per minute. At an 85 percent level of exertion, your target would be 145 beats per minute. Therefore, the target heart rate that a 50-year-old would want to aim for during exercise is 85 to 145 beats per minute.
But theres an easier way to figure it out if you want to skip the math: Wear a fitness tracking device, or exercise on a treadmill or other machine that calculates target heart rate for you, Blaha suggests.
Taking Your Heart Rate
Generally, to determine whether you are exercising within the heart rate target zone, you must stop exercising briefly to take your pulse. You can take the pulse at the neck, the wrist, or the chest. We recommend the wrist. You can feel the radial pulse on the artery of the wrist in line with the thumb. Place the tips of the index and middle fingers over the artery and press lightly. Do not use the thumb. Take a full 60-second count of the heartbeats, or take for 30 seconds and multiply by 2. Start the count on a beat, which is counted as zero. If this number falls between 85 and 119 bpm in the case of the 50-year-old person, he or she is active within the target range for moderate-intensity activity.

What Things Affect Heart Rate
Other than exercise, things that can affect your heart rate include:
- Weather. Your pulse may go up a bit in higher temperatures and humidity levels.
- Standing up. It might spike for about 20 seconds after you first stand up from sitting.
- Emotions. Stress and anxiety can raise your heart rate. It may also go up when youâre very happy or sad.
- Body size. People who have severe obesity can have a slightly faster pulse.
- Medications. Beta-blockers slow your heart rate. Too much thyroid medicine can speed it up.
- Caffeine and nicotine. Coffee, tea, and soda raise your heart rate. So does tobacco.

These intensities are called training zones and are expressed relative to HRmax. For instance, a light aerobic training session would be prescribed below 75% HRmax, while training at threshold will induce physiological change.
Overall, some exercise is better than no exercise for your cardiovascular health. Accumulating 150 minutes of exercise per week is the minimum requirement for health benefit. Exercising at your maximal heart rate is not necessary to achieve these benefits. Athletes can use training zones, relative to HRmax, to achieve optimal adaptation and enhance endurance performance.

How To Determine Your Max Heart Rate
Measuring your heart rate is an important part of monitoring your health. Calculating your max heart rate is one way to ensure you dont overexert yourself during rigorous exercise and to better measure your fitness progress.
Knowing your max and resting heart rate will give you more comfort and control when it comes to exercise intensity and your overall health. Exercising at the correct intensity can help you get the most out of your physical activity and making sure youre not pushing too hard or too little. The most common way to find your maximum heart rate is by using one of the many age-related equations. One of the most popular is the Fox formula: 220 Age = MHR.
According to the American Heart Association, before learning how to calculate and monitor your target training heart rate, you should know your resting heart rate. A good way to check is in the morning after youve had a good nights sleep and before you get out of bed. The average ranges should be:
- For children 10+ and adults: 60-100 BPM
- For well-trained athletes: 40-60 BPM
Measure Your Resting Heart Rate
- First sit quietly for 5 minutes or do this before you get out of bed in the morning. Place two fingers gently on either your carotid artery or on your radial pulse . Count how many pulses you feel for 15 seconds, and then multiply that number by 4.
- For example, if you count 15 pulses, thats a RHR of 60 beats per minute .

Measuring your heart rate is any easy way to gauge your health, as it provides a real-time snapshot of your heart muscle function. For most adults, a the number of heartbeats per minute while at restranges from 60 to 100 beats per minute. A normal heart rate can vary from person to person. However, an unusually high or low resting heart rate can be a sign of trouble.
Higher Maximum Heart Rate With Lower Fitness
Healthy non-athletes almost reach their true maximum heart rate during an all-out test of maximum oxygen uptake. In our research, we usually add five heart beats to the highest heart rate achieved during a cardiopulmonary exercise test, but according to our new results that is three beats too many. The study also indicates that women and men have similar maximum heart rates, and that persons with below-average fitness generally have higher maximum heart rates than fitter persons.
The study includes 107 men and women between 22 and 70 years of age. They all had their maximum oxygen uptake tested at our lab, and then performed a standardized maximum heart rate test a few days later. The results show that the real maximum heart rate was 2.2 beats higher per minute than the maximum heart rate achieved during the test of oxygen uptake.

What Is Maximum Heart Rate
Maximum Heart Rate is the amount of beats a heart makes in a minute under maximum stress.
Max HR is used as a benchmark for maximum output the athletes body can produce. Knowing that number enables the athlete and his coach to structure the training process around specific training intensities or training zones.
Maximum heart rate can vary significantly from person to person. In fact, high or low Max HR is neither good nor bad. Its just what a person is born with.
Instead, using it as a reference to build a structured training plan focused on specific exercise intensities is what makes all the difference.
All 5 of the training zones are defined as a percentage of maximum heart rate. Which is why its critical to determine maximum heart rate that is accurate to achieve desired results from training.

When Is The Best Time Of Day To Work Out
Trying to find the best time for exercise? The truth is, its personal! Follow these tips to figure out what fitness routine works best for you.
Dawn, dusk or dead of night whens the best time to work out? Well, that depends on whens the best time for you, because the benefits of physical activity depend upon how consistent you are.
You might have heard that the best time to exercise is early in the morning to get your metabolism going or to avoid unexpected distractions during the day that could derail your workout. But if youre not a morning person, it may not work for you to try to get up at dawn to work out. The key is to do whats most likely to work for you consistently.
If your schedule isnt predictable, you may need to be flexible and have a plan for various times of day.
If you find that working out too late in the evening keeps you from falling asleep easily, shift your exercise session earlier in the day or try less intense, more mindful forms of movement.

How To Calculate Maximum Heart Rate With A Field Test
Besides estimations and tests, you can calculate max heart rate by putting on your running shoes, firing up your heart rate monitor, and heading out into the real world.
You wont need fancy laboratory equipment for the field test but youll still get an accurate and personal estimation of your maximum heart rate. The premise is simple: you warm up properly and then do an exercise that brings you close to your maximum effort.
Please note that for a maximum effort field test its best to call a friend and have them join you, just to be on the safe side. Also, make sure you have some hard training under your belt from recent weeks.
Should You Be Tracking Your Heart Rate
Understanding your MHR can help you make sure you’re exercising at the proper intensity for your goals. Heart rate-based exercise personalizes your training to take it to the next level, so if it’s a possibility for you, consider investing in a wearable heart rate monitor, Cheng says, or try a workout class like Orangetheory Fitness, where every participant wears a heart rate monitor.
Just don’t let your heart rate become the sole focus of your workout. “If you find yourself taking extra lengths of time to calculate formulas, distracting you from your workout, it’s best to practice on rest days or hire a professional to monitor your heart rate for you,” Cheng says.

The Maximum Heart Rate In Your Fitness App Is Just An Estimate
If you are already going to the effort of tracking your workouts its important to get accurate data. While general data can show you important trends and give you a rough estimate of your effort and improvements over time, you can get much more accurate data by making sure that you have a few simple settings correct. One of the most important metrics that you need to get right is your maximum heart rate. Accuracy is key in heart rate training.
Maximum heart rate is the highest possible heart rate that your body is able to get to. This represents your maximum intensity. This is the value that represents pushing yourself to your absolute physical limits. When you first download your fitness app youre only seeing an estimate based on your age.

Food As Fuel Before During And After Workouts
Your body is your vehicle, so you have to keep your engine running when you work out. That means fueling up your body by eating the right foods and drinking the right fluids, in the right amounts at the right times.
The American College of Sports Medicine says, Adequate food and fluid should be consumed before, during, and after exercise to help maintain blood glucose concentration during exercise, maximize exercise performance, and improve recovery time. Athletes should be well hydrated before exercise and drink enough fluid during and after exercise to balance fluid losses.You dont have to adhere to a rigid schedule and there are no hard-fast rules, said Riska Platt, M.S., R.D., a nutrition consultant for the Cardiac Rehabilitation Center at Mount Sinai Medical Center in New York. But there are some things you should do before, during and after you work out.
How Do You Find Your Pulse
The easiest place to find your pulse is in your wrist.
- Turn your hand so that your palm is facing upwards.
- Now place the three middle fingers from your other hand over your wrist below the base of your thumb.
- Press lightly to feel the pulse under your fingers. If you cant feel anything press slightly harder.

Genetics contribute more to maximum heart rate than physical fitness. Your HRmax will be the highest heart rate you reach. The heart will reach a plateau at which it cannot beat any faster, regardless of how much you increase the workload.
Furthermore, what is the estimated maximum heart rate for a 21 year old? Target heart rate during moderate intensity activities is about 50-70% of maximum heart rate, while during vigorous physical activity it’s about 70-85% of maximum. Know Your Numbers: Maximum and Target Heart Rate.
| Age | Average Maximum Heart Rate, 100% | |
|---|---|---|
| 20 years | 100-170 beats per minute | 200 bpm |
Additionally, how do you calculate age predicted maximal heart rate?
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 .
What is a dangerously high heart rate when exercising?
According to their calculations, maximum heart rate is around 220 beats per minute minus the person’s age. Therefore, a 20-year-old’s maximum heart rate would be around 200 bpm .
How To Find Your Real Maximum Heart Rate
by: Shin Ohtake, Fitness & Fat-Loss ExpertAuthor of MAX Workouts, The Ultimate Lean Body Fitness Program
Exercising within your target heart rate zone has long been accepted as a standard training protocol, but what if I told you that the formula for calculating your max heart rate is inaccurate? And that even the doctor that created the formula admits to being completely surprised at how the medical and fitness communities have made it the standard formula, without anyone actually doing any extended research.
Heres the real story on how the formula for calculating your max heart rate came about :
Can you imagine if your MHR was 160, but according to the formula your MHR was supposed to be 185? You could push your self until you passed out and still not reach your calculated MHR. Or, on the other hand, what if your MHR was actually 200, but the formula calculated it to be 180? You would always be training at sub-par intensities, wondering why the people around you were sweatin up a storm when you barely broke a sweat.
The truth is that the popularity of the formula was more about timing than about exact science. It was available at just the right time, when people wanted an easy way to objectively figure out an intensity that would satisfy filling the criteria for both the medical field as well as the fitness field.
So what is the best way to find out how hard you need to train, without going into the danger zone? Well, you have a couple of options.
