What Is The Fat
Your target heart rate is a number that shows your heart is working hard enough â and that you’re burning a worthwhile number of calories â during exercise.
A person’s specific target heart rate depends on his or her age: The older you are, the lower your target should be. But generally, it should be between 50 to 85 percent of your maximum heart rate , according to the American Heart Association .

Is there a certain target heart rate that encourages your body to burn more fat? The simple answer is yes.
Exercising at around 70 percent of your MHR will encourage your body to use more energy from fat, while exercising at a higher heart rate will encourage your body to use more energy from carbohydrates, according to a February 2011 review published in the journal Clinical Nutrition Espen.
Staying in the so-called fat-burning zone might seem like the best option if you’re looking to lose weight. But in fact, that’s not necessarily the case.
Determining Your Maximum Heart Rate
The most accurate method to determine your maximum heart rate is a lab test, but you can also determine it on your own.
You can estimate your maximum heart rate with the following formula:
Max Heart Rate = 220 your age
This is a very rough estimate and doesnt produce the most reliable result, but its a starting point. Be aware that your max heart rate is affected by your physiology, which is affected by age but also influenced by many other factors.
Trying to establish a reliable result from variables you can measure statically is essentially impossible.
If you have a heart rate monitor , you can determine your maximum heart rate doing a ramp incremental test. This simply involves you exercising wearing a HRM, starting at a sustainable pace and increasing the intensity of your activity every so often until you cant go any faster.
The number on your HRM at that point is an accurate personal estimation of your max heart rate. You can perform a ramp incremental test running, rowing or an assault bike.
The most accurate way to calculate your max heart rate is a laboratory test. These are usually conducted with a trained professional in a laboratory with high-tech equipment.
Finding Your Resting Heart Rate
Your resting heart rate can help you to determine how fit you already are or aren’t! The lower your heart rate is when you are doing nothing, the more physically fit you are. A high heart rate can put you at risk of various types of heart disease.
To find your resting heart rate, find a watch or clock that has a second hand. Before you get out of bed in the morning, find your pulse either on your wrist or on the side of your neck using your index and middle finger. Dont use your thumb. Count how many beats you feel in 10 seconds, then multiply this by 6. For example, if you count10 beats in 10 seconds, 10X6 = 48 beats per minute . This is your resting heart rate.

Ultimately, exercising at 70 to 85 percent of your target heart rate will help you burn more calories, allowing you to reach your weight loss goal faster. Still, any type of physical activity that raises your heart rate will help you burn calories and lose fat, provided youre also taking steps to eat healthfully.
Moderate workouts thatll get you to 50 to 70 percent of your max target heart rate are things like:
- brisk walking

What Is The Fat Burning Heart Rate
Your heart rate is the number of times your heart beats per minute. How many times your heart beats depends on multiple things like activity levels, gender, weight, genetic factors, Your heart rate is usually a good indicator of how intense your workout is for you.
Notice the for you. For example an elderly, inactive lady might be doing high-intensity exercise by climbing stairs while a professional athlete has to sprint to get high-intensity exercise.
In general, when someone is just sitting down, a persons heart rate is between 60-100 beats per minute. Your heart rate when not doing anything is considered to be your resting heart rate. These numbers are a fairly flexible estimation. For example, if you exercise a lot, chances are your resting heart rate is lower than 60 beats per minute.
Being outside these numbers is no reason to start panicking just yet but you might want to talk about it with your doctor.
When you exercise your heart rate goes up. The more intense the exercise the higher.
The fat burning heart rate also known as the weight loss heart rate is the intensity zone at which your exercise burns the most fuel from fat instead of fuel from carbohydrates.
Ways To Assess Fat Burning
When measuring exercise intensity, youâll consider how you feel and your actual heart rate.
How do you feel? The first way to measure the intensity of your workout is by taking note of your perceived exertion. This differs from person to person. What may seem like a difficult run to one person could feel like a simple jog to another. This is a subjective measure of how your workout is going.
Heart rate. Measuring the intensity of your workout with your heart rate is a more objective way to look at it. The higher your heart rate while working out, the higher your exercise intensity is. This also means youâre more like to achieve fat burning in your exercises.
An activity tracker can track your heart rate for fat burning and cardio. These wrist monitors will help you keep track of your perceived exertion and how that correlates with your heart rate. This will help you get a better idea of when youâre actually in a fat-burning state.

What The Fat Burning Hr Zone Is Useful For
While theres no reason to think of it as the best heart rate zone for weight loss, there is still value to working out in the fat burning zone in some cases. In particular, it can be useful for endurance athletes in training and competition.
For example, a distance runner who stays in their fat burning HR zone during a race can conserve energy and tap into their quick-to-break-down reserve fuel supply for a burst of speed at the finish.
It is also possible to train for much longer durations of time when exercising in this zone.
How Do You Calculate Your Maximum Heart Rate
In order to figure out which heart rate training zone youâre working in, you first need to know your maximum heart rate. This is the most output your heart can handle during exercise.
The easiest way to calculate your maximum heart rate is 220 minus your age. While this is a very general tool, it is not the most specific and exact. Itâs difficult to get someoneâs actual maximum heart rate, because that would require field testing someoneâs heart at their actual maximum exercise output, which is cumbersome. For these purposes, 220 minus age is a good starting point, knowing that not everyone of the same age has the same maximum heart rate .
< p class=”pro-tip”> 220 – = Maximum heart rate < /p>
As an example, someone who is 25 would find their maximum heart rate like this:
< p class=”pro-tip”> 220 – 25 = 195 bpm< br/> < strong> 195 bpm< /strong> is the maximum heart rate.< /p>

The Truth About Your Fat Burning Zone
As you can see, the fat burning zone is also the lowest intensity zone. Seems counterintuitive right? The reason why its called the fat-burning zone, is because your energy metabolism is primarily focused on utilizing stored body fat, instead of carbohydrates as its primary fuel source when you work out at lower intensities.
The problem with this however, is that this can easily be misinterpreted. Its a common misconception that working out at a lower intensity will burn more body fat. Working out at a lower intensity will utilize more body fat for fuel, that is true, however its really about increasing your intensity and burning more calories, which will ultimately burn more body fat.
Significance Of Heart Rate
To determine where your intensity lies, you must first figure out your maximal heart rate. The maximal heart rate is age dependent, for as we grow older, the heart beats a little more slowly. To find maximal heart rate, subtract your age from 220. The fat burning and cardio zones are defined as a percentage of this maximal heart rate.

Ways To Measure Your Heart Rate
If you’re now thinking about measuring your heart rate to see how effectively you’re burning fat, there are a number of ways in which you can do so, with many of them thanks to modern technology:
What Is Your Fat
Your body requires a continuous supply of energy to function. Energy is derived from the foods you eat, which come in the form of carbohydrates, protein, and fats. As you digest those macronutrients they are broken down into their simplest forms, . These molecules are transported through your blood stream and converted in your body as energy in the form of Adenosine Triphosphate .
At rest your body utilizes both glucose and fatty acids for energy production. Your fat-burning zone simply refers to a target heart rate or exercise intensity at which you burn recruits more body fat for fuel as opposed to glucose. So what zone, is the fat burning zone?

The Fat Burning Zone Has No Afterburn Effect
When you exercise at low exercise intensities, you burn very few calories after the exercise is completed. When you exercise intensely such as during a HIIT workout, there is a metabolic disturbance that burns calories after the workout is completed. This is known as the afterburn effect.
Estimates of the afterburn effect vary wildly depending on the exercise method, the intensity of the workout, and even how its measured.
In a study by Dr. Christopher Scott and the University of Southern Maine, the total calorie burn of low intensity exercise vs. high intensity exercise was examined. A low intensity exercise group cycled at a steady rate of 3.5 minutes. The higher intensity exercise group required three 15 second sprints as fast as the subjects could run.
What was the difference in calorie burn? Quite substantial.
The cycling group burned 29 calories vs. 4 calories for the sprinting group during the exercise. But when you take into account the calories burned after exercise, or the afterburn effect, the numbers look much different 39 calories burned for the cycling group vs. 65 calories burned for the sprinting group. A surprising 95% of the total calorie burn occurred after the sprinting exercise!2 Keep in mind the cycling group exercised for almost 5x longer than the sprint group .

Fat Burn Target Heart Rate
The target heart rate is calculated based on 70% of the MHR.
Weve used the range of 64-76%, according to the CDC,The centers for diseases control and prevention. visit source in our calculations but another publication in the National Library of MedicineNational Library of Medicine. visit source gave the optimal heart rate for fat oxidation to be between 60.2% and 80%.
Though this represents are more substantial overlap between moderate and vigorous exercises, however, we look at it the midpoint for fat burn target heart rate remains roughly 70% of MHR.
From the table below, youll notice that the older you get the lower your fat burn target heart rate.

Studies have shown that both short-term vigorous exercises and longer duration moderate exercises are equally capable of ensuring weight loss through the burning of body fats.National Institute of health visit source The only difference is the timing. On the basis of this vigorous exercises are deemed to be more time-efficient but this may not be for everyone.
To achieve weight loss goals within the fat-burning heart rate zone, you may have to engage in your workout for up to 30 minutes. The longer you carry on, the more rewarding it gets.

Achieving The Ideal Heart Rate To Burn Fat
The best workouts to maintain the fat-burning heart rate may vary from person to person. Try to monitor your heart rate during different activities to see where you are then go from there.
For fat burning, its best to stick with moderate activity. To gauge this, try the talk test, which is where you try to talk during your exercise. If you cant talk, youre likely working at vigorous levels. If youre slightly out of breath but can still maintain a conversation, youre probably working at moderate levels and may be in your fat-burning zone.
Here are some exercises that can help you reach your fat-burning zone:

Your Expert Guide To Target Heart Rate And Weight Loss
Climb on an elliptical machine or check your wearable fitness tracker, and youll likely find an array of settings aimed at helping you optimize your workout. Toggling through the menu, you might see a prompt to pick a fat-burning or cardio mode for your sessionand then scratch your head in confusion. Whats the difference? And is one mode more effective than the other at helping people lose weight?
These labels, which reflect workout intensity and are usually tied to heart rate, can be puzzling, acknowledges cardiologist Nieca Goldberg, MD, medical director of the Womens Heart Program at New York University. Read on as Dr. Goldberg and other leading experts decode what each zone really means in terms of weight loss, fitness, and healthand offer evidence-backed reassurance that the best workout is the one that works for your life.
The difference between fat-burning and cardio zones
First things first: Your body needs fuel for physical activity, whether youre biking, swimming, or rearranging living room furniture. That fuel comes from two main energy sources: stored fat, or stored carbohydrates in the form of glycogen released from muscle tissue.
In marketing-speak, the fat-burning zone is generally billed as the setting for people hoping to lower their percentage of body fat. Meanwhile, the cardio zonein which the body uses glycogen for energyis billed as a way to boost cardiovascular endurance.

Are There Optimal Heart Rate Zones For Lowering Glucose Spikes
Based on one study of 11 men comparing intermittent exercise throughout the dayâpre-meal exercise and post-meal exerciseâthereâs no wide consensus on which is the best to lower glucose. However, the study found that brief intermittent exercise throughout the day was more helpful in lowering glucose spikes around breakfast, specifically< sup> 4< /sup> .
This study also confirms that exercise can, and will, at any time, support lowering glucose spikes. Both low- and high-intensity exercise can blunt glucose spikes. And individuals should try different intensities to see how their bodies respond.
Once again, rather than being concerned about a particular target heart rate or heart rate training zone in order to lower a glucose spike, just get moving. Exercise enhances a glucose-stabilizing lifestyle, which is a tool to optimize your health.
What’s The Target Heart Rate For Fat
The target heart rate to burn the most fat, and even continue to burn fat after youve finished exercising is 70-85%. This is known as the ‘afterburn effect’, and it happens because your high-intensity workout has caused a metabolic disturbance which means calories are still being burnt even when you’re finished your workout.
The fat-burning myth
There’s a rumour perpetuated by many fitness and health magazines, which states that the optimum fat-burning ‘zone’ is between 55-65% of your maximum heart rate. Experts have dispelled this myth and put it to bed many times, but it’s worth reaffirming.
The concept of the ideal fat-burning zone came about because at lower exercise intensities , more fat is burned relative to glycogen, the substance that stores carbohydrates in your body. That might sound great – but when you look at the calorie burn, the figures are very different.
High intensity exercise will burn more calories than low intensity workouts, and this is key when trying to create that coveted ‘afterburn effect’.
A bit of science
A study was carried out at the University of Southern Maine, which involved two groups of people doing different types of exercise. One group was cycling at a steady rate for 3.5 minutes . The other group performed three 15-second sprints, running for as fast as they could in a short space of time .
