Understanding the VO2max score chart and how to improve it

28. Oktober 2025 ca. 19 Minuten

You’ve probably come across VO2max on your fitness watch or in a health app. A VO2max score chart can give you a quick idea of your aerobic fitness—from below average to excellent. But what exactly does this number mean, and why is it so important for your health and well-being?

In this guide, we’ll explain in simple terms what VO2max measures, how to interpret it using charts, and, most importantly, how you can improve it. We’ll also look at why getting the right nutrients—the levels of which you can check with a blood test from mybody-x.com—is the invisible foundation of your endurance.

What your VO2max score really says about your fitness

Think of your body as an engine. Every movement, from a leisurely stroll to an all-out sprint, requires energy. This energy is produced directly in your muscle cells, and oxygen is the most important “fuel” for it. The more oxygen your engine can take in and burn, the more power it delivers.

That’s exactly what VO2max measures. It’s the gold standard for measuring your endurance capacity and shows how many milliliters of oxygen your body can use per minute and per kilogram of body weight during maximum effort (ml/min/kg). A high VO2max simply means that your cardiovascular system is in top shape and your muscles are supplied with oxygen efficiently.

More than just a number for athletes

Of course, VO2max is a key metric in competitive sports. But it matters to anyone who cares about their health. It’s a strong indicator of your overall physical condition and even your longevity. A good score is directly linked to:

• A stronger heart: With every beat, your heart pumps more oxygen-rich blood through your body.
• More efficient lungs: Your lungs can filter and absorb more oxygen from the air.
• Better circulation: Your body creates more tiny blood vessels (capillaries) to deliver oxygen to every last muscle cell.
• Healthier cells: Your cells use the oxygen delivered more effectively to produce energy.

A higher VO2 max value is not only a sign of athletic fitness, but also an important marker of your cardiovascular health and general well-being. It shows how well your body can supply itself with energy.

The foundation for performance and well-being

More and more health-conscious people are measuring their maximum oxygen uptake to keep track of their progress. As a general guide, remember that untrained men often have a value of around 40 ml/min/kg, while untrained women average around 35 ml/min/kg. If you want to learn more, you can find additional information about maximum oxygen uptake at Helios Gesundheit.

A good oxygen supply is the foundation for all physical performance. But for your body to transport oxygen at all, it needs an important helper: iron. Iron is a key component of hemoglobin, the “oxygen taxi” in your red blood cells. If you’re low on iron, not enough oxygen reaches your muscles – and your performance drops. Find out more in our article about what iron deficiency means for you.

A blood test from mybody-x.com, such as a nutrient test, gives you clarity about whether you’re getting the optimal amounts of essential nutrients. This way, you can make sure you’re giving your body the best conditions to improve your endurance and achieve your health goals.

VO2 max value tables for men and women by age

Let’s get down to brass tacks: How fit are you really? The number on your sports watch is one thing, but what does it mean compared with other people of your age and gender? That’s where VO2 max tables come in. They’re your personal compass for quickly and easily assessing your endurance.

Take a look at the values and find out where you stand – around average, in the good range, or perhaps even at the top? This comparison is the first step toward setting realistic goals and seeing your progress in black and white.

This infographic gives you a quick overview of typical average values and the general differences between men and women.

As you can see, men have a slightly higher VO2max value on average. This isn’t due to greater dedication to training, but to natural physiological reasons.

Why age and gender matter

Before you dive into the tables, let’s briefly clarify why we distinguish by age and gender in the first place. Men naturally tend to have more muscle mass, a larger heart, and more hemoglobin in their blood—all factors that support oxygen transport in the body and therefore lead to a higher VO2max value.

At the same time, it’s perfectly normal for maximum performance to gradually decline over the years. It’s a biological process we all go through. But here’s the good news: you’re in control! With regular training, you can not only slow this process down, but even take your fitness to a whole new level.

VO2max value table by age and gender

This table shows the average VO2max values (in ml/min/kg) for men and women, divided into different age groups and fitness levels from poor to excellent. This lets you compare your value directly.

Age group	Gender	Very poor	Poor	Average	Good	Excellent	Superior
20–29	Men	< 35	35–41	42–48	49–54	55–60	> 60
	Women	< 29	29–33	34–39	40–45	46–51	> 51
30–39	Men	< 33	33–39	40–45	46–51	52–57	> 57
	Women	< 27	27–31	32–37	38–43	44–49	> 49
40–49	Men	< 31	31–37	38–43	44–49	50–55	> 55
	Women	< 25	25–29	30–35	36–41	42–47	> 47
50–59	Men	< 29	29–35	36–41	42–47	48–53	> 53
	Women	< 23	23–27	28–33	34–39	40–45	> 45
60+	Men	< 27	27–33	34–39	40–45	46–51	> 51
	Women	< 21	21–25	26–31	32–37	38–43	> 43

Important: These tables are a great guide, but they’re not set in stone. Your personal value also depends on your training history and genetics.

These reference values are based on broad population data and provide a good representation of the average. Surveys, such as those conducted by the Robert Koch Institute (RKI), show that men between the ages of 20 and 29 often have values around 35–40 ml/min/kg, while women of the same age are at 27 to 30 ml/min/kg. After turning 30, the value often decreases by 5 to 10% per decade if you do nothing about it. If you want to delve deeper into the subject, you can read more about the background to VO2max values here.

Above all, what the tables show is the huge potential within you. Even if your value is only “average” today, you can improve significantly with the right training. In the next section, we’ll look at how to interpret your value correctly and what it means for you.

How to properly interpret your personal VO2max value

Reading a number on your watch is one thing. But what does that number really say about you and your fitness? That’s the key question. Maybe you saw in the VO2max value table that your value is considered “average.” But what does that mean in real life?

Your VO2max value isn’t a fixed label, but a living indicator of your physical condition. So many things influence it. Don’t see it as a school grade, but as the starting point of your personal journey toward greater strength and health.

More Than Just Age and Sex

Of course, the tables give you a rough initial guide by breaking down values by age and sex. But to really understand your result, we need to dig deeper. Your personal value is made up of many individual factors, like a mosaic.

These include, above all:

• Your genetics: Yes, your genes play a part. Some people naturally have a more efficient cardiovascular system.
• Your training level: Are you an old hand at sports, or are you just getting started? A well-trained body is an expert at using oxygen.
• Your body weight: The value is given in milliliters per kilogram of body weight. It makes sense that your weight plays a direct role here.
• Altitude: Do you live or train in the mountains? The thinner air there forces your body to adapt and use oxygen more efficiently.

Your VO2max value isn’t a verdict, but a tool. It shows you where you stand and gives you the chance to decide where you want to go. Use it as motivation, not as a source of pressure.

What Your Value Means in Everyday Life

Let’s make this concrete. Say your value is “average.” That’s a great starting point! It means your cardiovascular system is fit for everyday life and you have a healthy foundation to build on. Climbing stairs or carrying your weekly groceries home? Probably no problem for you.

At the same time, an “average” value shows that there’s still untapped potential. Imagine being able to chat easily with friends on your next walk without getting out of breath, or finishing your weekend bike ride with a smile. That freedom is exactly what an improved VO2max value can offer.

From Understanding to Action

Interpreting your value is the first step toward making the most of your physical potential. It’s about recognizing your strengths and working deliberately on your weaknesses. Once you understand what you can adjust, you can really get going.

One factor is often overlooked: proper nutrient intake. Your training can be perfect, but if your body lacks the building blocks for oxygen transport and energy production, you'll hit an invisible wall. We've also put together detailed information in a further article on how to understand and improve your VO2 max value.

A nutrient test from mybody-x.com can give you valuable clarity here. It shows you in black and white whether an unnoticed deficiency in iron or essential vitamins might be holding back your progress. This gives you the ideal foundation not just to keep your engine running, but to take it to a whole new level.

How to reliably measure your VO2 max

Okay, now you know what the number on your watch or in your performance report means. But the crucial question is: how do you get a reliable reading in the first place? There are different ways to determine your VO2 max - from highly accurate lab tests to simple methods you can do yourself.

The good news is that you don't necessarily have to go to a lab. Every method has its pros and cons. We'll introduce you to the most common ones so you can find the one that best suits your goals and budget.

The gold standard: laboratory spiroergometry

If you want to know exactly, there's no getting around spiroergometry. It's the gold standard of performance diagnostics, trusted by professional athletes too. You run or cycle wearing a breathing mask while the intensity keeps increasing - until you really can't go on.

The mask measures the exact composition of your breath. This makes it possible to determine precisely how much oxygen your body can absorb and use under maximum exertion.

• Advantage: It doesn't get more precise than this. You get not only your VO2 max value, but also other extremely useful data such as your individual heart rate zones or your anaerobic threshold.
• Disadvantage: It takes a lot of effort and isn't exactly cheap. Expect to pay around 150–250 euros and book an appointment at a sports medicine institute.

Convenient and close to the mark: the fitness watch

Modern sports watches from Garmin, Polar, and others are now remarkably good at estimating your VO2 max. They use clever algorithms that combine a whole range of data: your heart rate, heart rate variability, pace, and of course personal details such as age, sex, and weight.

Your smartwatch gives you a good estimate of your VO2max value, which is perfect for tracking trends and progress over time. For absolute precision, however, the lab remains unbeatable.

Of course, it can't match the accuracy of a lab measurement. But for most recreational athletes and anyone who cares about their health, that's perfectly adequate. Consistency is the most important thing: the value is especially useful for tracking your progress over weeks and months. If your watch shows an increase from 42 to 45 ml/min/kg, that's a clear sign that your training is working.

The classic at-home option: field tests

You don't necessarily need expensive equipment to get a rough idea of your VO2max. So-called field tests let you easily put your endurance to the test yourself. The best-known one is the Cooper Test.

It's very simple to do:

1. Warm up thoroughly.
2. Run on a flat, measured course (for example, a 400-meter track at a stadium) for exactly 12 minutes, as fast as you can.
3. Measure the exact distance you covered in that time.

Afterwards, you can use a formula to calculate your estimated VO2max value. Although tests like these aren't as precise as a watch or a lab test, they give you a solid indication of your fitness.

Whatever method you choose, remember: A single reading is just a snapshot. Your daily condition, stress, or even the weather can affect the result. What's much more important is checking your values regularly and keeping track of how they change. To make sure your body is optimally prepared for this kind of exertion, it may be worth checking key health markers. With the at-home health tests from mybody-x.com, you can make sure you're getting the nutrients you need and create the best conditions for reliable results.

Effective strategies for increasing your VO2max

So now you know your VO2max value. That's the first important step. But now the real work begins: targeted improvement. The good news is that your maximum oxygen uptake isn't set in stone. With the right training, you can really upgrade your cardiovascular system and take your endurance to a whole new level.

We’ll show you which training methods have proved most effective in practice for really getting your internal engine revving. But first, one thing to note: The best training is of little use if the invisible foundation is missing - giving your body the right nutrients.

Intensity as the key to success

To noticeably increase your VO2max, you need to challenge your cardiovascular system. You need to give it a reason to adapt and grow stronger. The best way to do this is to train regularly at or near your performance limit. Two types of training are absolute game changers.

High-intensity interval training (HIIT) HIIT is like a turbo boost for your fitness. The principle is simple: You alternate between very intense effort and short periods of active recovery. This method forces your heart to work at full capacity and pump a maximum amount of oxygen-rich blood to your muscles.

• For beginners: Run 400 meters at a fast pace 4 to 6 times. In between, take a break by walking easily for 400 meters.
• For advanced runners: Complete 5 rounds of running for 4 minutes at 90–95% of your maximum heart rate, with a 3-minute jog recovery between each round.

Tempo runs With this method, you maintain a consistently fast but still manageable pace for an extended period - say, 20 to 40 minutes. It feels strenuous, but you can just about keep it up. Experts call this training at the anaerobic threshold. It trains your body to use oxygen more efficiently and break down the lactate that builds up more effectively.

Training provides the stimulus, but the actual improvement happens during recovery. Give your body time to recover and the right nutrients to get stronger.

The effect of targeted endurance training is truly impressive. Studies show that even after just a few months of regular training, significant improvements in VO2max of 10 to 30% are possible. For example, an untrained adult can increase their VO2max from around 35 ml/min/kg to 45–50 ml/min/kg within 3 to 6 months.

Don’t forget the foundation: long, easy sessions

As important as intense sessions are, they’re only the tip of the iceberg. You build the foundation for your endurance with long, easy runs or bike rides. These sessions in the base training zone (at around 60–75 % of your maximum heart rate) improve capillarization in your muscles. This means more tiny blood vessels form, transporting oxygen even more effectively and deeper into your muscle cells.

Your body needs the right fuel

You can follow the smartest training program in the world, but if your body lacks the essential building blocks, you’ll keep hitting an invisible wall. Certain nutrients are absolutely vital for oxygen transport and energy production.

• Iron: Without iron, there’s no hemoglobin in your red blood cells. Without hemoglobin, oxygen can’t reach your muscles efficiently. Your performance suffers, no matter how hard you train.
• B vitamins (especially B12 and folic acid): These vitamins are essential not only for red blood cell formation but also play a central role in your cells’ energy metabolism.
• Magnesium: This mineral is involved in over 300 metabolic processes that are important for muscle contraction and energy production.

A deficiency in these areas can sabotage your progress without you even realizing it. You may just feel tired and unfocused, and wonder why your training simply isn’t delivering the results you want. The cause could be a nutrient deficiency.

A nutrient test from mybody-x.com can help clear things up. It precisely analyzes your blood values and shows you in black and white whether your nutrient levels are optimal or whether you should take targeted action. This gives you the perfect foundation to finally reap the rewards of your hard training.

And if you want to take things a step further, you can tailor your training even more by understanding how your body genetically responds to different stimuli. Our article about the DNA-based training plan explains how you can tailor your training even more to suit you.

Frequently asked questions about VO2 max

You’ve now learned a lot about VO2 max, the charts, and the right training strategies. But, as is often the case, a few questions still come up when you get into the details. Here, we clear up the most common myths and give you clear answers so you can put any remaining doubts to rest.

How quickly can I improve my VO2 max?

This is one of the most fascinating questions, and the answer is a clear one: it depends on where you're starting from. Your current fitness level is the deciding factor.

As a beginner, you can look forward to quick and motivating results. Your body isn't used to the exertion yet, so it responds extremely well to new training stimuli. An increase in your VO2max value of 10 to 20% within the first three months is absolutely realistic. So after just a few weeks, you'll notice that climbing stairs or sprinting for the bus feels easier.

If, on the other hand, you're already a well-trained athlete, the improvements will naturally be smaller. Your system is already working very efficiently, and to get even better, you need to apply very targeted stimuli. At this point, it's more about fine-tuning, for example by varying interval lengths or intensities. Progress comes more slowly, but it's just as valuable.

Why is the VO2max value often lower in women?

This difference, which you can also see in any VO2max value chart, is purely biological. It says absolutely nothing about an individual woman's performance or fitness level. It's important to understand these physiological differences to interpret the values fairly.

The main reasons for this are:

• Body composition: Women naturally have a higher body fat percentage and less muscle mass. Since VO2max is measured relative to total body weight, this results in a lower value mathematically.
• Heart size: On average, men have a larger heart. This means more oxygen-rich blood can be pumped into circulation with each beat.
• Hemoglobin levels: Men have an average higher concentration of hemoglobin, the protein responsible for transporting oxygen. More “oxygen taxis” mean greater transport capacity.

It's important to emphasize that both sexes have an excellent ability to improve their VO2max through targeted training. Their potential for relative improvement is absolutely comparable.

What role do nutrients play in VO2max?

You can train as hard as you want, but if the engine doesn't get the right fuel, it will never reach its full potential. Your training provides the stimulus, but your body needs the right building blocks to adapt and get stronger. Nutrients are the often-overlooked foundation.

Iron is a prime example. It is the central component of hemoglobin. Iron deficiency inevitably leads to a poorer oxygen supply to your muscles. The result: You feel sluggish, your performance stagnates or even declines.

But other micronutrients are essential too:

• B vitamins (e.g., B12, B9): They are essential for forming healthy red blood cells and play a key role in energy metabolism.
• Magnesium: This mineral is involved in hundreds of processes necessary for muscle contraction and energy production.

An unnoticed deficiency in these nutrients can sabotage your progress. A nutrient test from mybody-x.com can show you exactly whether such deficiencies are holding back your performance and help you reach your full potential.

Which sports are best for increasing VO2max?

The classic answer is running, and that’s true. But it’s far from the only way to reach your goal. In general, all endurance sports that engage large muscle groups and really get your cardiovascular system working are ideal.

Some of the most effective sports include:

• Cycling: Especially uphill or during intense intervals, cycling is an excellent VO2max booster.
• Swimming: As a full-body sport, swimming challenges your entire system while being particularly easy on your joints.
• Rowing: Like swimming, rowing works your arms, legs, and core, quickly raising your heart rate.
• Cross-country skiing: Not without reason, it is considered one of the most demanding endurance sports, with top athletes recording some of the highest VO2max values.

The best approach is often a combination, also known as cross-training. This mix not only makes things more fun, but also reduces the risk of overuse injuries. It can even help you improve your performance faster.
