Know Your Resting and Max Heart Rate
Keeping track of your heart rate is vital for endurance athletes. In this article Suunto partner PerfectPace explains the ins and outs.
Knowing your max heart rate is an important guide for athletes. It gives you a roof for your training and indicates the level of intensity. On the other hand, one of the first signs of overtraining syndrome is an elevated resting heart rate. For endurance athletes doing high volume training this is essential to watch out for.
Identifying your maximum and resting heart rate is vital for the calculation of training zones. Particularly for endurance training these numbers are very important and they are not hard to come to. But there are a few things to consider.
How to Find Your Maximum Heart Rate
You have probably heard of the formula 220 minus age to get your maximum heart rate. Some say that this formula is not too exact but all in all the results are ok. Unfortunately that is not the case. In most cases the result is way off.
A Norwegian study on more than 3300 healthy women and men has tested their maximum heart rate. The graphic below shows the result. What we can see is that the average values for the whole population is on a straight line. But for most individuals their maximum heart rate is far from that line. The conclusion is that the formula works for the average global population but not for an individual.
When looking at the graph it is also evident that no formula can calculate the individual maximum heart rate. The results are just too scattered. The only way to get to your max HR is via a test.

How to Test Your Maximum Heart Rate
The maximum heart rate should be tested in your sport. Runners should run and swimmers swim. Triathletes should do a run test. The heart rate is the highest in running of all three sports. A max HR test is VERY demanding. You need to go to your limit and that will hurt.
A typical test for runners looks like this:
Warm up for at least 10 minutes. Now increase your tempo for 5 minutes until you get out of breath. This is the time to start a one minute spurt. It will hurt but you need to max out. Depending on your ability to push yourself you'll get close to your maximum heart rate.
To make the most of this kind of intensity training, consider using the Suunto Run sports watch. Designed specifically for runners, it accurately tracks your heart rate—even during short bursts—and helps you understand how close you are to your maximum capacity. With dedicated running modes, recovery insights, and real-time pace and effort metrics, Suunto Run keeps you in tune with your body, so you can train smarter and go further.
How to Find Your Resting Heart Rate
Like for the maximum heart rate there is no formula to calculate your resting heart rate. The resting heart rate is even more individual than the maximum heart rate. Some sport watches like Sunnto Run can measure your pulse while sleeping. In the morning you will have your resting heart rate.
If you don’t have such a device you can simply measure your heart rate right after you woke up. Untrained have a resting heart rate between 60-80 bpm. Endurance athletes might have only 35 bpm. The reason for such differences are adaptations to the cardiovascular system. The heart gets stronger and more efficient when under high load but also when resting.
What Is a Normal Resting Heart Rate?
For adults, a typical resting heart rate falls between 60 and 100 beats per minute.
In general, a lower resting heart rate indicates a more efficient heart and stronger cardiovascular fitness. For instance, highly trained athletes often have resting heart rates as low as 40 beats per minute.
Changes of the Maximum and Resting Heart Rate
The heart rate changes during your lifetime. Simply by getting older. A new born baby has a resting heart rate of 130-140 and it drops with every year. This is the reason why the formula 220 minus age came up. But there are a lot more factors than just age that influence your heart rate all the time. Therefore you should test again from time to time to make sure your training zones match your physiology.
But there are also short term changes in your heart rate. You won’t be able to reach your max heart rate every day. Also the resting HR is changing from day to day up to 15 beats per minute. reasons can be a cold or over training. By checking your resting heart rate regularly you can spot abnormal stress levels early and adapt your training.
What Is a Dangerous Heart Rate?
A dangerous heart rate refers to a resting heart rate that is abnormally high or low and may indicate an underlying health issue. However, context matters—well-conditioned athletes, for example, often have resting heart rates below 60 bpm, which can be perfectly healthy.
Several factors influence whether a heart rate is dangerous, including age, fitness level, sex, medical history, and the use of certain medications. Symptoms such as dizziness, chest pain, shortness of breath, or fainting—especially when paired with an abnormal heart rate—may signal a serious problem and should prompt medical attention.
Always consult a healthcare provider for heart rate concerns that seem unusual or are accompanied by other symptoms.

How to Start Working Out Again After a Knee Injury? (8 Tips)
Imagine this: you're working out or playing any sport, and just as you leap for a rebound, something twists in your knee. You hear a pop, and pain shoots through your leg. Days later, the doctor confirms what you feared: that it's a knee injury. The first question that will arise in your mind will be, Can I work out again? If so, how do I start safely?
Well, Knee injuries are among the most common issues athletes and fitness enthusiasts face. Whether it's a strained ligament, torn meniscus, or overuse, such injuries are very common and can significantly impact your ability to move, exercise, or even complete daily tasks. However, fortunately, recovering from a knee injury is not as difficult as some might presume. In this article, we will dive deep into how to start working out again after a knee injury through the best eight recovery tips. So let's get started:

8 Tips to Start Working Out Again After Knee Injury
Here are the 8 best tips to start working out again after the knee injury. These tips are professional, practical, and safe and aim to support your return to fitness in a careful, evidence-based way.
1) Adopt a Positive and Patient Mindset
First things first, stay positive and optimistic. Recovering from any injury, particularly a knee injury, isn't just about the body; it starts with the mind. A positive and patient mindset is your foundation for successful recovery. Therefore, it is important to understand the process and recognize that the recovery process will be gradual. There will be some bad days and good days.
You can plan out by setting goals that are short-term but realistic. For example, walking pain-free for 10 minutes can be a big milestone. Celebrate those wins. Patience will allow your body the time it needs to rebuild, and a positive mindset will keep you motivated even when progress feels slow. Therefore, instead of focusing on what you can't do yet, focus on what you can.
2) Stay Connected with Your Fitness Community
Injury can sometimes lead to feelings of isolation. Especially if you're used to regular workouts or group training, feeling isolated during recovery is really common. However, staying in touch with your fitness community can be helpful, as it will provide emotional support and encouragement.
So, during the recovery period, check in with workout buddies. You can consider joining virtual workout groups or participating in fitness forums where others share their recovery journey. It is important because even a light conversation about fitness can keep you engaged and inspired by reminding you that you are still part of the community.
3) Manage Your Weight to Reduce Joint Stress
You know how important it is to maintain a healthy body weight, and it becomes even more important when you are recovering from injury. It is because extra weight can place additional stress on your injured knee, which can slow down the healing process. Contrary to this, effective weight management helps reduce inflammation and speeds up healing.
That's why it is important to manage your weight, and you can do it by making small changes in your diet. Focus on consuming a balanced diet rich in whole foods, including lean proteins, vegetables, fruits, and healthy fats. Besides this, try to avoid sugary or processed food, as they can cause inflammation. You don't need a strict diet plan; just be mindful of your choices.
Moreover, if your healthcare provider permits, do gentle activities like swimming or stationary cycling to stay active without aggravating your injury.
4) Avoid Heavy Lifting and Deep Squats (Early On)
During the early stages of recovery, it is advisable to avoid heavy lifting and deep squats. It is because these movements exert significant pressure on the knee. So the question arises, what else can you do?
Instead of heavy lifting or squats, opt for light resistance exercises with slow and controlled movements. You can use resistance bands, bodyweight workouts, or lightweight dumbbells. In addition, you can also shorten your range of motion. For example, instead of going deep for full squats, you can do half squats. For better understanding, you can take services from a physical therapist or certified trainer, as they can provide personalized guidance and ensure proper form.
5) Focus on Core and Glute Strengthening
When recovering from a knee injury, it might sound strange to work on your abs and glutes. But these muscle groups are crucial. A strong core improves balance and stability, while strong glutes support your hips and knees during movement.
Therefore, focus on the muscles surrounding the knee by incorporating exercises like bridges, clamshells, side planks, and bird dogs in your routine. These movements will enhance overall posture and alignment by not putting pressure on your knee but still building strength in areas to protect it.
Remember, consistency is key here. At first, you can start doing 10-15 minutes of these strengthening workouts 3-4 times a week. You can gradually increase the intensity as your strength improves.
6) Rebuild Strength Gradually
Rebuilding strength gradually helps you avoid setbacks and ensures long-term success. Therefore, start with low-impact movements: walking, cycling, and basic bodyweight exercises, and increase the intensity or resistance only when your knee feels stable and pain-free.
Also, make sure to monitor your progress. Track down what exercises you did, how long you worked out, and how your knee felt. Keeping a recovery journal can help you track improvements and identify any activities that may require adjustment.
7) Ease Back Into Workout Slowly
Returning to your workout routine should feel like a soft landing, not a crash. Therefore, carefully create a modified workout plan for your first few weeks back. Focus on low-impact activities like yoga, Pilates, swimming, or light elliptical sessions. It is because these options can provide cardiovascular benefits without overloading your joints. Try following the 10% rule: increase your workout duration or intensity by no more than 10% per week.
Remember, it's okay to take breaks. Listen to your body, and don't rush just because you're excited to get back into shape.
8) Listen to Your Body—Stop if There's Pain
This one is really crucial and might be the most important tip of all. Pain is your body's way of saying, "Slow down." While a little soreness can be normal, sharp or lingering pain is a red flag that you should never ignore.
During an exercise, if you feel discomfort in your knee, stop immediately and evaluate your activity. Do not try to push through the pain, as doing so makes things worse. Also, always warm up before the exercise session and cool down afterwards. Gentle stretching and mobility work can support joint health and flexibility. Consult your physician if symptoms persist.
Bonus Tip: Track Your Progress with the Suunto 9 Peak Pro Smartwatch
As you are rebuilding your fitness routine, tracking your progress becomes essential. That's where the Suunto 9 Peak Pro Smart Watch comes in.

All you need to do is prioritize a positive mindset, maintain connections with your support network, focus on a healthy diet, and ease back into workouts with caution.

VO₂ Max Explained: How to Improve It for Better Health
VO₂ max is one of the most important indicators of cardiovascular fitness and endurance performance. It reflects how efficiently your body uses oxygen during exercise. As a runner, as well as someone looking to enhance a general well-being, increasing your VO₂ max can enhance your performance. This guide tells you how it works and how you can improve it and monitor it using Suunto watches.

Conclusion
What Is VO₂ max?
VO₂ max is the amount of oxygen that your body is able to consume in one minute per kilogram of body weight (ml/kg/min). It tells the quality of your heart, lungs, and muscle coordination that helps to drive your body motions. The higher the VO₂ max level, the more energy your body can produce aerobically, without becoming easily fatigued. Scientifically speaking, it is a product of three systems acting as one:
• Oxygen intake (lungs)• Oxygen transport (heart and blood)• Oxygen usage (muscle mitochondria)
VO₂ max scores for elite endurance athletes typically range from 60 to 85 ml/kg/min. For healthy adults, average values tend to be around 35–50 for men and 27–43 for women, depending on age and fitness level. By monitoring this number, you gain a clear target and a reliable way to track your fitness progress.
Why Improving VO₂ Max Matters
VO₂ max not only provides an estimate of performance, but also of health and life expectancy. In a 2016 study published in Progress in Cardiovascular Diseases, it was discovered that VO₂ max was among the strongest predictors of all-cause mortality, stronger than blood pressure or smoking. Improving VO₂ max is directly connected with:
• Cardiovascular fitness: Increased VO₂max enhances blood circulation and delivery of oxygen in the body.
• Longer life: VO₂ max is shown to be one of the strongest predictors of longevity, even stronger than cholesterol or blood pressure level
• Improved output: To a runner, a bicyclist, and a swimmer, it implies increased stamina and recovery rates.
"Your VO₂ max tends to decrease as you get older, which over time can make it harder to do simple activities… Keeping fitness high helps you maintain autonomy and translates to a longer life." — Kate Baird, Exercise Physiologist
How Is VO₂ Max Measured?
1. Laboratory Testing: In this test, a run is performed on a treadmill while wearing a mask that measures oxygen consumption. It is accurate; however, it is also costly and laborious.
2. Wearable Estimation: Suunto watches estimate VO₂ max using your heart rate, speed, and GPS information. The estimates are somewhat accurate and ideal to use daily.
The Suunto app updates your VO₂ max after every training session, so you get immediate feedback on what you have just achieved.
Factors That Affect VO₂ Max
Your VO₂ max score is determined by a number of factors:
• Genetics: Some individuals are born with greater oxygen processing potential, but all individuals can become better. • Age: VO₂ max decreases with age (~8–10% per decade), but constant training allows maintenance of VO₂ max. • Sex: Men tend to score higher on VO₂ max, owing to bigger heart/lung capacity.• Training Level: Newbies are likely to experience rapid progress compared to experienced players. • Lifestyle: These factors include sleep, diet, hydration, and levels of stress. Learning about them will enable you to be realistic in goal setting and remain focused on matters within your control.
How to Increase VO₂ Max
Structured cardiovascular stress is required in order to increase your VO₂ max- training your body to be more efficient in its use of oxygen. The following are tested strategies:
1. Endurance (Steady-State) Training
Aerobic base: A moderately intense run between 30 and 90 minutes develops your aerobic base, and it strengthens your heart. Shooting at 60-75 percent of maximum heart rate.
2. High-intensity interval training (HIIT)
Alternate between short bursts of high effort and recovery.Example: 4x 4 minutes at 90-95% of your max heart rate with 3-minute rests intervals.HIIT is a proven method to boost VO₂ max and cardiovascular efficiency quickly.
3. Sprint Interval Exercise (SIT)
They are intense and brief in nature, e.g., 30-second all-out sprints with long intervals. SIT boosts the fast-twitch muscle fiber and cardiovascular changes.
4. Cross-Training
Use cycling, swimming, or rowing to avoid overuse injuries.
5. Lifestyle Adjustments
VO₂ max improvements require adequate recovery to allow the body to adapt and build aerobic capacity. Focus on:
• Sleep: 7-9 hours/night, in order to facilitate adaptation.• Nutrition: Eat whole foods, drink plenty of water, and make post-exercise meals a priority.• Stress: Constant levels of stress inhibit aerobic improvement- focus on rest days and mindfulness.
Step-by-Step Training Tips
Use these tips to structure your VO₂ max training effectively:
Warm-Up & Cool DownAt the beginning of each session, take 10-15 minutes to jog or move dynamically. Finish up with simple running and stretching.

Full Guide on How to Run Longer Distances
If you want to get in shape or just wish to improve your overall health, long-distance running is an incredible option. It's budget-friendly and offers benefits such as strengthening the cardiovascular system and boosting endurance. However, to run longer distances efficiently, you need to follow proper tips and tricks to avoid exhaustion. Don't know what those are? Let's find out!
Part 1. Is It Healthy to Run Long Distances?
Yes, running long distances is healthy as it significantly improves your bone density and heart health. In addition, it helps you with weight management. According to Dr. Dan Meyer, chief of cardiac transplantation at Baylor Scott & White Health in Dallas:
"Any type of aerobic exercise has a positive effect on the heart."
However, don't directly jump into running longer distances. Rather, gradually increase your mileage to ensure you reap maximum health benefits and don't end up with injuries. Many experts suggest increasing your mileage no more than 10 to 15 percent every week to avoid issues like stress or fracture.
Is It Better to Run Long or Short Distances?
Whether to run longer distances or shorter ones really depends on your strength and fitness goals. For instance, if you excel at quicker and high-density workouts, short-distance running might be your cup of tea. It targets your body's fast-twitch muscle fibers, leading to a burst of energy and also increasing your speed during other sports, such as baseball.
On the other hand, if you look forward to boosting your stamina, you should definitely opt to run longer distances. It focuses on slow-twitch muscles that efficiently utilize oxygen and keep you powered up for an extended period. You enjoy better concentration and enhanced endurance.
Part 2. What Is the 80% Rule in Running?
The 80% rule in running implies that 80% of your weekly running should be at a slow pace and intensity, while the remaining 20% should be high-intensity efforts. This 80/20 rule was first popularized by Dr. Stephen Seiler, a sports scientist at the University of Agder in Norway.
Beginners can use the 80/20 rule to create a strong aerobic base for future running goals by engaging mostly in low-intensity runs.
Professional runners can prepare for their competitive goals by personalizing their workouts' speed and intensity as per the 80% rule.
It's advisable to follow this rule when you run longer distances to improve your running economy. This improvement is because when you run at a slow intensity, your body is able to use fat as a fuel source, conserving glycogen for when you need it the most. Know that the better your running economy, the less energy you'll utilize to run a certain distance.
Part 3. What Is the 3-2-1 Method Running?
The 3-2-1 method is actually a workout structure that involves intervals of different durations and intensities. To put simply, in this method, runners do:
3 minutes hard running followed by a 1 minute jog, repeat this several times
Then, 2 minutes hard running followed by 1 minute jog
Finally, 1 minute hard running followed by a recovery jog
This model is specifically designed to enhance your mobility and strength while maintaining a focus on recovery. You can hit your fitness goals and achieve milestones without feeling burnt out.
Benefits of 3-2-1 Method Running
If you want to dig deeper into the benefits of 3-2-1 method running, here's an overview:
Targets Every Part of Your Fitness: Intense training and hard running helps build your muscles and functional power. It's a cardio exercise and studies suggest that a cardio session is associated with living a longer life.
Maximum Flexibility: The 3-2-1 offers incredible flexibility in your workout routine. You may engage in hard, long distance running or do short-distance, low-intensity jogs to hit the mark while still relaxing.
Part 4. How to Track and Improve Your Long Runs Efficiently?
Now that you are aware of whether it is healthy to run longer distances and the different approaches you can adopt, here's an overview of how you can track and improve your runs:
1. Focus on 3 Core Elements
One of the things you can do to track your long runs is to monitor three key metrics: pace, distance, and heart rate. Pace tells you how fast you are running per mile or kilometer. By keeping a track of it, you can better understand your endurance levels and overall improvement. Distance is actually the measure of how far you've run (the ground you've covered). You should measure it regularly to oversee your performance and gradually increase your mileage by no more than 10 to 15 percent. Another important thing to look at is your heart rate, which should fall within the low to moderate zone.
2. Use a Sports Watch
We suggest wearing a GPS-enabled watch that precisely measures your pace and distance. If you need a recommendation, then Suunto Run sports watch is the ideal option. This watch is extremely lightweight, weighing around 36 grams. Therefore, wearing it won't make you uncomfortable and seamlessly blend in with your lifestyle.
The AMOLED screen offers swift navigation and crystal clear display. What truly sets it apart is its 12-day battery life, which ensures the watch doesn't die when you run longer distances. You even get to enjoy 20 hours of training time which can be extended to 40 hours by using the power saving mode.
Besides, this watch offers multiple modes including track, treadmill, and trail running. For detailed insights, it tracks your training load, heartbeat, and Training Stress Score (TSS). You can use this data to understand your overall progress and what areas need improvement.
Suunto Run supports sleep analysis as well as Bluetooth so you can jam on your favorite music while hitting your goals. The best part? The stainless steel bezel and gorilla glass keep the watch away from damage, ensuring good ROI.
3. Rely on a Running App
Another option is to use a running app, such as Strava, Nike Run Club, or Runkeeper. Start by downloading the running app on your phone through Google Play Store or App Store. Set up your profile by entering important information such as gender, birthday, and profile photo if necessary. Next, open the app and start your run.
The app will use your GPS to track your distance, pace, and elevation. You may also get to know about the calories burned, helping you optimize your diet for maximum strength training and running.
Part 5. Tips to Run Longer Distances
Do you know around 50 million people run in the United States alone? Yes, it's true! So whether you want to start your running career or boost your professional marathon performance, here are some tips that you should follow:
Fuel Your Body: If you think that training is the only way to run longer distances, you are wrong. You should take an appropriate quantity of macronutrients including carbohydrates, proteins, and fats. Have a mix of everything including protein shakes, fruits, and vegetables so your body and muscles can recover after hard running sessions.
Hydrate Strategically: Dehydration can cause cramping when you run longer distances. To avoid this and maximize your energy levels, you should be properly hydrated. An important scientific study states that on days that you do not run, you should aim for drinking at least 2.5 - 3.5 liters of water per day. If you run for <60 minutes, you should increase this amount by a factor of 1.3.
Focus on Strength Training: Injuries are a common occurrence when you run long distances. However, you can avoid that by focusing on strength training. Engage in squats, deadlifts, and lunges to improve your muscle strength. Crunches, planks, and sit-ups should also be part of your workout routine so that your arms and shoulders feel equally strong.
Conclusion
Whether you are a professional runner or just starting out, it's important to do proper workout and take a balanced diet to run longer distances. But that's not all; you also need to invest in a high-quality sports watch designed for runners like Suunto Run that keeps an eye on your pace as well as tracks your recovery, sleep, and training load. You can definitely run longer as well as better with it.

What Is HRV and How to Improve It
Heart Rate Variability (HRV) refers to the natural variations in the time intervals between consecutive heartbeats. These differences may seem small, but they are crucial for understanding how our body functions. Tracking HRV provides insight into our ability to adapt to stress and recover, which is essential for overall health and performance.

Frequently Asked Questions
Conclusion
What Is Heart Rate Variability(HRV)?
HRV, or Heart Rate Variability, represents the variability in the time gaps between heartbeats. Unlike heart rate, which shows how many times the heart beats per minute, HRV measures how these intervals fluctuate. Higher variability means our nervous system is flexible and capable of quickly responding to changes in our environment.
Why Does HRV Matter?
HRV reflects the balance between the sympathetic nervous system, which activates and prepares us for action, and the parasympathetic system, which calms us and aids recovery. High HRV indicates a strong ability to recover and manage stress, while low HRV may be associated with chronic stress, fatigue, or certain health conditions, though it should be interpreted alongside other health indicators. That’s why HRV monitoring is a valuable tool for athletes and anyone looking to improve their health and wellbeing.
Main Factors Influencing HRV
Heart Rate Variability (HRV) is affected by a variety of factors that together shape how well we adapt and recover from daily challenges. Understanding these factors can help you better monitor your health and make smarter lifestyle choices. Here are the key influences on HRV:
Age: HRV naturally tends to decrease as we get older.
Gender: After adolescence, women generally have slightly higher HRV than men.
Genetics: Our inherited traits determine our baseline HRV levels.
Health Status: Chronic illnesses, obesity, heart conditions, and sleep disorders can lower HRV.
Lifestyle Choices:
Quality sleep is one of the most important factors for maintaining high HRV.
A nutritious diet supports healthy variability.
Regular, moderate physical activity usually increases HRV.
Alcohol, caffeine, and smoking negatively impact HRV.
Staying well-hydrated is key for optimal body function and HRV.
Psychological and Emotional Stress: Prolonged stress reduces the body’s ability to recover, which shows up as lower HRV.
External Environment: Factors like temperature, noise, and pollution can also influence HRV.
Average HRV values vary, so it’s important to track your own results over time. For example, younger adults often have HRV between 60 and 100 milliseconds, while values tend to decline with age.
Normal HRV Ranges and How to Interpret Them
Normal Heart Rate Variability (HRV) values vary depending on age and your personal baseline. There is no single "good" HRV number that applies to everyone. What matters most is tracking long-term trends and comparing them to your own average rather than focusing on individual readings.
When your HRV is within your personal baseline range, it means your body is in balance and functioning well. This state is called "balanced." On the other hand, if your 7-day average HRV falls outside your baseline range, it indicates an "unbalanced" status.
It's important to note that higher HRV values don't always mean better health. Sometimes, unusually high HRV can be a sign of overtraining, especially when caused by a large amount of low-intensity physical activity. In these cases, the parasympathetic nervous system is highly active, trying to restore balance. This phenomenon tends to occur more often in endurance athletes, particularly after prolonged periods of excessive low-intensity training.
If your HRV is significantly lower than your baseline, the status is considered "low," which may indicate a need for extra rest and recovery.
How to Increase HRV?
Improving your Heart Rate Variability (HRV) involves making small but consistent lifestyle changes that support a balanced nervous system. Here are some simple, evidence-based tips:
Regular Physical ActivityExercise is one of the best ways to boost your HRV and overall health. Aerobic activities like running, swimming, cycling, or brisk walking have been shown to improve HRV. Avoid excessive training or prolonged inactivity, as both can negatively affect it.
Mindfulness and Controlled BreathingPractices such as meditation, mindfulness, and breathing exercises (like diaphragmatic or box breathing) can reduce stress and increase HRV. These techniques activate the parasympathetic nervous system, helping your body recover faster.
Healthy NutritionA diet rich in vegetables, fruits, quality proteins, and healthy fats (such as the Mediterranean diet) supports nervous system function and improves HRV. Avoid processed foods, excess sugars, and unhealthy fats.
Adequate Quality SleepGetting 7 to 9 hours of quality sleep per night and maintaining a consistent sleep-wake schedule are crucial for improving HRV and emotional balance.
Proper HydrationStaying well-hydrated is essential for optimal nervous system function and maintaining good HRV. Dehydration can quickly lower your variability.
Somatic and Heart-Focused Breathing ExercisesSimple breathing exercises that stimulate the vagus nerve can increase HRV in just a few minutes. Many people have noticed immediate relief and improved recovery through these techniques.
These are some of the key ways to support and improve your HRV. Consistency and mindful tracking are important to see lasting benefits.
HRV Measurement & Practical Recommendations
Today, there are numerous smart devices and sports watches that enable accurate measurement and tracking of HRV. Among them, Suunto GPS watches — such as the Suunto Race, Suunto Race S, and Suunto 9 Peak Pro — stand out as reliable tools for athletes and anyone looking to improve their health. These devices make it easy to monitor your heart rate variability, gain valuable insights, and set recovery and performance goals.
To get the most accurate HRV readings, it is important to measure your HRV at the same time every day, ideally right after waking up, before getting out of bed. This routine helps minimize the impact of factors like physical activity or stress on your results.
It is crucial to focus on long-term trends rather than reacting to single data points. Short-term drops and fluctuations in HRV are normal and may reflect recent lifestyle changes such as poor sleep, stress, or illness. However, if you notice persistent and significant decreases in your HRV over days or weeks compared to your personal baseline, it may be a sign to adjust your habits or seek professional advice.
Some practical ways to support healthy HRV include:
Regular physical activity with balanced intensity
Prioritizing quality sleep and maintaining a consistent sleep schedule
Managing stress through meditation, mindfulness, and breathing exercises
Eating a balanced diet rich in nutrients
Staying well-hydrated and limiting caffeine and alcohol intake
Frequently Asked Questions
Is higher HRV always better?Not necessarily. While higher HRV generally indicates better adaptability and recovery, it’s important to consider your individual baseline and current circumstances. Exceptionally high HRV values can sometimes indicate abnormal or overtrained states, so context matters.
Is it normal for HRV to drop after exercise?Yes, it is quite common for HRV to temporarily decrease after intense physical activity. This reflects the body’s stress response to exercise. However, with proper rest and recovery, HRV should rebound and even improve over time.
Do day-to-day swings in HRV matter?Minor daily fluctuations in HRV are normal and usually not a cause for concern. It’s the long-term trends and overall patterns that provide meaningful insight into your health and recovery status.

A good HRV during sleep depends on your age, fitness, and overall health. For most healthy adults, values between 40 and 100 milliseconds (rMSSD) are typical. Instead of focusing on one number, it's better to track your own trends over time — staying close to or above your personal average usually means your body is recovering well.
Conclusion
Monitoring your Heart Rate Variability (HRV) is a powerful way to better understand your body’s response to daily stresses and recovery needs. By paying attention to the factors that influence HRV—such as sleep quality, nutrition, physical activity, and stress management—you can make informed lifestyle choices that enhance your overall well-being and performance.

Expert Breathing Tips For Running: Find Your Rhythm and Run Better
If your legs feel strong but your breath gives out mid-run, you're not the only one. Many runners face this challenge, and often the fix is simpler than expected.
Breathing may seem automatic, but when it comes to running, it takes awareness and technique. Poor breathing can slow you down, drain your energy, and make even short runs feel harder than they should.
Let's walk through this post to learn essential skills that can change your entire running experience. We will explain the proper breathing technique for running, how to find a rhythm that supports your pace, and how smart tools like the Suunto Run sports watch can support your training by helping you monitor effort and recovery.
So here we go!
Part 1. The Basics of Breathing While Running
Deep breathing is a fantastic way to release your body and get rid of any remaining air. Before you begin running, warm up a bit, roll your shoulders, carefully turn your torso, and let your chest unfold. It enables your lungs to have more room to take fuller and more comfortable breaths.
In short, we can say that to feel fully comfortable while running, it is important to explore the best breathing technique for running.
Why Is It Hard to Breathe While Running?
The moment you start running, your body suddenly demands more oxygen, but unfortunately, our body is not used to breathing deeply and steadily. Instead, we fall into shallow chest breathing, which just doesn’t support you once your legs start pushing harder. So, there is a huge need to learn proper breathing technique for running.
In addition to breathing techniques, several subtle factors can further complicate the situation:
Bad Posture: Slouched or bent shoulders cause your lungs to get squashed, and the amount of air you can take in is reduced.
Tighten Upper Body: You feel tight in the arm or the neck region, affecting your ability to breathe freely.
Anxiety or Panic: You start panicking when you feel that your breathing is going wrong, and this state doubles the issue. Thus, that head spiral also leaves you with a feeling that you have lost control of your breathing.
No Breath Training: Most runners train their legs but never practice breathing. Your lungs need training too.
Why Is Proper Breathing Technique for Running So Important?
There is nothing too complex about running strategies, just some minor adjustments which can make a difference the next time you are on the road. Let’s glance through the significance of breathing techniques.
It increases stamina by delivering consistent oxygen to your body, helping you go longer without tiring quickly.
A proper breathing pattern prevents side cramps that often come from shallow or erratic breathing.
It keeps your nervous system calm, so you don’t feel panicked or tense during harder efforts.
Your pace becomes smoother and more natural when your breath and steps are in sync.
When your breathing and walking are coordinated, the rhythm of your movement becomes more regular and natural.
Adding deep breathing helps your muscles by supplying them with the oxygen they require to continue their work.
Being mindful of your breath adds attention to your run and makes you mentally alert.
How to Clear Lungs for Running?
Starting your run with tight, shallow breaths? Let’s fix that with this quick pre-run breathing drill.
Inhale through your nose for 3 seconds
Exhale through your mouth for 6 seconds
Repeat for 1–2 minutes while walking or lightly jogging
You don't need to wait for things to go wrong to start thinking about your breath. The truth is, it’s always better to get ahead of the problem than to fix it mid-run.
Those first few minutes of your warm-up are golden. Use them to ease in, find a rhythm that feels good, and just breathe. Slow it down. Let your breath settle into your body. No pressure, just presence.
It may be an easy thing to say, but with such a beginning, a difference can be made in reality. This will help you get your breath and movement on the same rhythm, and this is the thing that makes this one of the most natural and effective breathing styles to run. It is not perfection but connection.
Part 2. Best Breathing Techniques for Running
Breathing is not about some special formula. It is discovering a pace that suits you, your pace, and your aims. Let's read on to find the proper breathing technique for running:
1. Breathing Through The Mouth And The Nose
Nose breathing gets a lot of attention—and for good reason. During easy runs, it helps filter, warm, and humidify the air you breathe. However, as your effort increases, your nose alone can't meet your body's oxygen demands. That's when mouth breathing kicks in to keep you going."
2. Belly Breathing Is Better Than Chest Breathing
A very important trick that you must not miss in this guide is belly breathing or deep breathing also referred to as diaphragmatic breathing. This method will make you move air very deep into the lungs and not merely puff into the chest. To do it, simply lie and put one hand on your belly and the other one on your chest. When you breathe, watch the movement in your belly as it goes up and your chest remains as though rained. It is that which you want to recapture when you run.
3. Syncing Your Breath with Your Stride
This technique requires some practice, but it is well worth it. Matching your breathing pattern with your foot strikes helps you maintain a steady rhythm and can also reduce the chances of side cramps.
Here's a simple breakdown:
Intensity
Breathing Pattern
Use Case
Easy run
Inhale 3, exhale 3 steps
Recovery or warm-up
Moderate pace
Inhale 2, exhale 2 steps
Long runs or steady workouts
Hard efforts
Inhale 2, exhale 1 step
Intervals or hill sprints
Part 3. How to Track Your Breathing and Performance While Running
No more guesswork. Monitor how your breathing responds to effort, heart rate, and pace—then fine-tune your performance on the go.
The Role of Heart Rate Zones
As your effort increases, so does your breathing. Monitoring your heart rate provides a clear indication of how hard your body is working.
Here's a quick cheat sheet:
Zone 1–2: Easy breathing, full sentences
Zone 3: Short phrases, starting to focus more
Zone 4–5: Quick, hard breathing. You’re pushing.
By staying aware of your zone, you avoid overreaching too soon. That helps keep your breathing stable longer.
How Consistent Breathing Helps Endurance
When your breath gets wild, everything else gets harder. But when is it steady? You save energy. Your muscles get more oxygen. Your brain stays focused. You feel more in control.Consistency here isn't perfection. It’s about returning to a rhythm, again and again, even as the run gets tough.
