Czech Tarzan: Natural Movement, Biohacking, and the Power of the Mind
Adam combines natural movement, longevity, and modern technology to find the best way to stay healthy, strong, and resilient.
Czech original:
Welcome to my very first interview on this platform—hopefully not my last, with a bit of luck.
Today, I invited a guest who proves that strength, movement, and health aren't just about what we do in the gym but about how we live every day. My guest calls himself the Czech Tarzan, and if you follow him, you know that it's not just a nickname but an entire lifestyle. Adam combines natural movement, longevity, and modern technology to find the best way to stay healthy, strong, and resilient.
We'll talk about what he does for longevity, his views on new fitness trends, and whether health technologies help or harm more than they benefit.
You call yourself the Czech Tarzan. What does that mean to you? Is it more about physical strength, mentality, or something else entirely?
I’d say it’s more about mentality. Initially, I picked this nickname primarily because of my appearance, but over time, I started realizing that it holds a deeper psychological and mental aspect for me. This persona represents nature, raw energy, a pure approach to life, maybe even randomness and spontaneity—qualities I want to embody.
I believe that in today’s hectic world, overloaded with information and dopamine-draining stimuli, this approach can be beneficial. It helps people focus more on nature, their bodies, and a more natural way of living.
So, I see a strong mental aspect to this alter ego or persona. Of course, it also represents muscle and strength, but I find the psychological aspect even more compelling.
Many people train primarily because they want to improve their physical appearance, but you focus on longevity and functional strength. What is the biggest mistake people make when trying to stay healthy throughout their entire lives?
For me, it's consistency.
A lot of people get motivated and dive into exercise, start eating healthy, or go through phases of focusing on recovery and sleep—but they don’t maintain it consistently.
It always comes in phases, and I think the key is to turn it into a true lifestyle—something that makes you feel good throughout your whole life, not just in a short-term cycle of "I want to lose weight for summer" or "I need to burn off the holiday weight."
You need to establish a routine—eating habits, movement habits—and integrate them in small, sustainable ways over the long term.
And just like my Czech Tarzan persona, everything should feel natural and not forced. You shouldn’t be doing something just because someone said it’s good for you, while secretly hating every second of it. That’s not an ideal approach.
At the same time, it’s a fine line because it’s important to distinguish between laziness and genuine intuition. Many people struggle to tell whether they don’t want to do something because they’re just lazy or because it’s actually not beneficial for them. That’s a really difficult skill to develop.
If you had to simplify fitness to its absolute minimum, what three activities or habits would you recommend for a long and strong life?
The number one, without a doubt, is sleep. And not just any sleep—it has to be consistent. The key aspects of sleep are regularity, depth, and duration.
So, how long you sleep, when you go to bed and wake up every day, and how good your sleep quality is—all of that matters.
The second pillar is movement. Movement is essential for our body's proper function, hormone regulation, and even appetite control. When you move correctly, you develop a natural sense of hunger and cravings that align with your body's needs.
And that leads to the third pillar—nutrition. When you train properly, your body activates protein synthesis, making it better at absorbing proteins and other nutrients. So, eating the right foods in combination with movement helps your body regenerate effectively.
I’d also add a fourth element—mental well-being and social interaction. If you’re doing all these things—sleeping well, eating right, and moving—but you’re alone and stressed, it won’t work.
Humans are social creatures; we thrive in tribes. Studies confirm that loneliness shortens lifespan. So, spending time with people who make you feel good, where you can be yourself without stress or pretense, is just as important.
In the past, you have tested various biohacking methods and approaches inspired by our ancestors. Which ones actually work, and which ones do you think are just overrated buzzwords?
Right now, I’m exploring this a lot with a clinic in Prague that offered me tests on epigenetics, DNA, RNA, and, of course, standard blood tests for liver, kidney function, cholesterol, and hormone levels.
In my opinion, these tests are useful if you track them over the long term because they help you see changes and adjust your lifestyle accordingly.
As for epigenetics, I’m still unsure. I don’t fully understand how these tests work or how reliable they are when they tell you that, based on your ancestral DNA, you have a higher risk of certain diseases.
I worry that it might be overestimated. There are so many factors that determine how at-risk you are for a disease, and even just knowing you "might" have a predisposition could be a psychological trigger.
That’s why I haven’t done genetic testing yet—I’m concerned it might act as a self-fulfilling prophecy. If someone tells you, "You’re predisposed to this and that," studies show that the placebo or nocebo effect is real. You might start experiencing symptoms just because you expect them.
So, I prefer to focus on the basics—monitoring blood pressure and heart rate variability, which can give a clear indication of overall health and stress levels.
Another great method is grip strength testing. Every morning, you can use a hand dynamometer to measure how much force you can apply. If one day your grip strength is significantly lower than usual, it might indicate that your body is fighting off an illness, so you can adjust your training accordingly.
And finally, the three simplest and most reliable biohacking indicators:
Skin health
Dental health
Stool quality
These will always provide the most accurate feedback on whether your lifestyle and diet are working for you.
What does your morning ritual look like? Do you have any habits that you consider essential for energy, longevity, and other key factors?
Definitely. Everyone has their own way of doing things, but for me, my mornings always start with rehydration. After a full night’s sleep, I want to replenish electrolytes and minerals—sodium, magnesium, potassium, the absolute basics. I use electrolytes made from negatively charged minerals sourced from the Great Salt Lake.
I also take a greens mix from Brain Market—spirulina, chlorella, minerals, vitamins. This is especially useful in winter when I don’t have as much access to fresh vegetables. I try to get my fiber and vitamins mainly from fresh produce, but in winter, supplementation helps. Then I have some additional supplements, though they’re more experimental, so I won’t go into detail.
After my morning supplementation, I turn on my walking treadmill, switch on infrared and near-red light therapy, and take a morning walk under infrared light. At the same time, I do breathing exercises and open the window.
Since it’s still dark when I wake up in the winter, I need to kickstart my body properly. So, I open the window for fresh air, turn on the infrared light, and walk on the treadmill while doing breathing exercises. During this time, I also respond to messages from clients waiting for training updates.
After that, I take a shower and brush my teeth. About an hour into my morning routine, I prepare my coffee. I add MCT oil and Shilajit, a mineral supplement made from Himalayan resin. This combination prevents cortisol spikes from coffee by slowing down caffeine absorption, while MCT oil further delays its onset.
Then, I head to the gym. That’s my morning routine.
You often talk about the importance of natural movement and outdoor training. Do you think the modern concept of gyms is becoming outdated?
To a certain extent, yes.
I think it’s great that many people use machines, weights, and all the equipment found in traditional gyms—because not everyone can handle bodyweight exercises. Unfortunately, we live in a time when many people struggle to do a single push-up or squat. They need to build basic movement patterns that they may have never developed before.
For that reason, gyms serve a good purpose. However, I think gyms should promote more natural movement. At the very least, they should have large windows for natural daylight and provide spaces for meditation or recovery methods.
In the U.S., this approach is becoming quite popular. There are gyms with cold plunge baths, saunas, infrared lights, and hydrogen therapy. There are so many options, and I think we’re slowly moving in that direction. In the U.S., these things are already mainstream, whereas in most gyms here, the best you’ll find is a tanning bed and maybe a sauna. But if gyms started evolving in this direction, it would be amazing.
As for natural movement and outdoor training, I don’t think people in the Czech Republic are ready to pay for it. Czechs would just say, “Why should I pay for something I can do for free in the forest?”
That said, it might still work. Some people go to the gym just to run on a treadmill without using any other equipment, so a natural movement training center could potentially find an audience as well.
What role does breathwork play in your training? Do you use breathing techniques for performance, recovery, or both?
Breathing is absolutely crucial.
And not just in a mechanical sense. A lot of people debate whether it’s better to breathe through the nose or mouth—which is important—but I focus more on breathwork in relation to posture. Am I breathing with a hunched back? Am I breathing shallowly into my chest? Or am I standing tall and breathing deeply into my diaphragm? I believe this plays a huge role.
Rather than fixating on whether to exhale while lifting a weight or lowering it, it’s more important to be aware of breath throughout the entire movement spectrum.
We’re now shifting towards the topic of technology and the future of health. Today, technology and health are deeply connected—we have smartwatches, AI-driven training plans, and countless innovations. What is your opinion on this? Do you think these advancements help us, or do they do more harm than good?
I think they definitely help us.
When it comes to smartwatches, though, it’s a bit tricky—similar to DNA tests. You might feel great, but if your smartwatch tells you, “You had a bad night’s sleep, you should rest today,” the nocebo effect can kick in. You start thinking, “Oh no, my stats are bad,” and even if you have a packed day, you end up being less productive because you’re fixating on those numbers.
That said, I like the approach of Brian Johnson, a well-known biohacker, who argues that we can’t rely solely on what our minds tell us. I agree with him to a certain extent.
I’ve experimented with both extremes—relying purely on intuition versus strictly following algorithms. When I only wore a regular analog watch, I would assess my energy levels and decide, “I slept well, I feel good.” But then laziness would creep in. I’d think, “I don’t really feel like working out today; maybe I should rest more.” It became very inconsistent.
The brain constantly tries to keep us in our comfort zone. But when I have accurate smartwatch data, and ideally also consult AI, I can see: “Wow, I actually slept great, my recovery is at 100%, and even if I don’t feel like it, I know I can perform at my best today.”
Conversely, if I feel like training but my recovery data says otherwise, I know I should genuinely take a rest day.
So I’ve come to believe that this technology is beneficial. I would even go as far as letting an algorithm make all my decisions. Instead of debating whether I feel like doing something or not, I would just follow what the algorithm determines is best for my health and do it.
Some experts argue that thanks to technology, we may be able to live much longer than we currently expect. Would you want to live to 150 years old if your body and mind remained strong?
Yes, absolutely.
This is actually something I discuss almost daily at the gym. Whenever I tell people I want to live to 150 or even 200 years, they always look at me like I’m crazy.
They say, “Oh no, I wouldn’t want that—I’d rather die earlier.” But I try to explain that the goal isn’t to spend another hundred years bedridden in a hospital. The goal is to extend the number of productive, vibrant years when you feel great. That should be the main objective, and I genuinely believe it’s possible.
Petr Mára once said something interesting: “If we can avoid dying in the next five years, we’ll probably live to at least 150.”
This is because of how fast artificial intelligence is progressing. One of the latest breakthroughs in AI-assisted healthcare was in brain tumor removal. Most people imagine that tumors look completely distinct from healthy tissue, but in reality, they blend in almost seamlessly. Surgeons struggle to determine whether they’ve removed the entire tumor or if some cancerous tissue remains.
AI can now detect this with incredible precision and predict whether any cancerous cells are left behind. I find that absolutely mind-blowing, and I think technological advancements in health are progressing at an incredible pace.
So yes, I fully believe that living to 150 is realistic. I’m very optimistic about it.
What is your opinion on AI trainers? Can artificial intelligence ever replace human intuition and experience in fitness?
Absolutely.
This ties back to what we talked about earlier—regarding smartwatches and tracking body metrics. AI or wearable devices can predict the state of the body with much greater accuracy than human intuition.
If a client tells me, “I feel kind of tired, I think I might be coming down with something,” as a trainer, I might say, “Alright, maybe you should take it easy today and skip training.”
But if that client sent me their data—or if they sent it to an AI trainer—artificial intelligence could predict much more precisely:
“Actually, you’re just being lazy, go work out.”
Or on the other hand:
“Yes, something might be off, take a rest day.”
What I believe AI can never replace, however, is friendship. Then again… even that is a tricky question.
The biggest value of a real trainer, in my opinion, is companionship. I am physically there with the person, spending time with them, listening to them, maybe even saying something silly or offering an opinion they don’t want to hear.
But that’s exactly the natural human quality that AI lacks. AI always processes things differently than a human. Humans have imperfections and flaws, but that’s what makes the experience with a real trainer unique. It’s about authenticity, about real interaction between two people.
And that, to me, is irreplaceable.
With the rise of VR fitness, biofeedback tools, and gamification, do you think people will train predominantly in digital environments in the future?
I’m not sure, I have mixed feelings about it.
I think the digital environment is more oriented towards laziness. I believe we’ll see an increasing divide—one group of people will withdraw more and more into the digital world, becoming less social and handling everything through technology. Shopping, work, friendships—it will all shift to digital platforms.
In some communities, it might start to resemble the Pixar movie Wall-E, where people are floating around in chairs with screens in front of their faces, completely unaware of the people sitting next to them.
At the same time, I think we’ll also see the opposite extreme—a strong resurgence of real, in-person interaction. There will be a growing interest in workshops, outdoor training camps, and survival retreats where people learn to start fires, practice yoga, climb trees, cold plunge, and run in nature. I believe this second group will expand rapidly. Many people will crave real, human experiences.
And even though VR and digital fitness will offer endless dopamine hits, the physical, real-world experience of movement will always be stronger and more natural. There will be a large group of people who will prioritize and seek out this kind of approach.
That’s the direction I want to move in—that’s where I want to grow and develop. I wouldn’t want to promote the trend of working out at home in VR.
If you could invent or improve one technology for health, what would it be?
Wow, that’s a really tricky question.
I think it would be… something for meditation and relaxation.
There are already so many technologies that help people push their limits—tracking heart rate for running, monitoring calories burned, sleep tracking, and more.
We have smart shoes with Bluetooth sensors, smartwatches, performance trackers—but almost nothing focuses on proper recovery. Sure, there are apps for breathwork, but there’s no truly comprehensive relaxation solution. I’d love to see a device that helps people establish an evening ritual.
Personally, I turn on calming music, dim the lights to red, roll out a yoga mat, and do breathing exercises. But it’s a bunch of separate steps that I have to manually set up.
Imagine a home kit that does it all—automatically adjusts the lighting, plays the perfect relaxation music, monitors your breathing, and gives you real-time feedback on how to breathe properly. I’m not sure exactly how it would work, but something that naturally helps people unwind. Maybe a special VR headset or a mask with pre-set relaxation modes.
That could be incredibly useful.
But this is just my first idea off the top of my head.
It’s no secret that our modern comforts are ruining us—less movement, more sitting, heavy reliance on processed food. Do you have any tips on how people today can reclaim a more natural way of living?
For me, one of the best decisions I made was getting a walking treadmill for home.
On days when I don’t go to the gym and I’m working from home—like today—I just turn on the treadmill and walk while I work. Right now, I have it off so I can focus on talking, but otherwise, it’s a great way to stay active and burn a lot of calories throughout the day. Walking is incredibly healthy, and it also prevents back problems caused by sitting hunched over all day.
Beyond that, movement improves blood circulation to the brain, which boosts focus and productivity. So, for anyone who works from home, a walking treadmill is an amazing investment.
Of course, when the weather is nice, I recommend going outside—to the forest, a park, anywhere in nature. And above all, running—it’s the most natural form of movement for humans. It doesn’t have to be super fast, you don’t need to track heart rate zones or pace—just go for a run, even if only for a short while. That’s how you start reconnecting with natural movement.
Would you ever have technology implanted in your body? For example, biosensors, neural chips, or exoskeletons to enhance performance?
That’s a great question. But I don’t think I would ever implant anything in my body.
I don’t even have tattoos, piercings, or anything foreign that would interfere with my body’s natural state. I believe in external enhancements—clothing, bracelets, necklaces, watches. These can improve appearance, and if they have smart sensors, they can help track health.
But the key difference is that you can take them off whenever you want. If I want a break, I can remove my watch, lie in bed, and be free from technology.
The same applies when I go out into nature—I want to be there, just myself, uninterrupted by any devices. That’s incredibly important to me.
That’s why I wouldn’t want something permanently implanted in my body. Even if it could theoretically be removed, it would still be something that doesn’t belong inside me. In this context, I firmly believe that nothing should be implanted into the human body.
Your philosophy on nutrition is strongly inspired by nature. What approach to diet do you recommend for longevity and better performance?
Low-frequency eating is, in my opinion, the most important factor.
This is mainly because, today, most people don’t eat because they’re truly hungry—they eat because they are addicted to food. They’ve been conditioned to eat at specific times, even when they don’t actually feel hunger.
You can easily test this by fasting. If you do a one-day fast, you start to notice when you genuinely feel hunger—when your stomach signals that your body truly needs food. The same happens after training—that’s when real hunger kicks in, not just cravings. There are scientific studies confirming that mild caloric restriction and occasional hunger have positive effects on health. That’s why I personally incorporate intermittent fasting.
As for the food itself, it should be as unprocessed as possible. It should be whole, meaning everything naturally found on our planet—meat, vegetables, legumes, grains. Anything I can take directly from nature, heat up if necessary, and eat—I consider healthy.
On the other hand, anything artificially produced, industrially processed, packaged, and labeled with a barcode is no longer primarily meant as nourishing food but rather as a product for sale. Food companies don’t care if I live a long life; they care about sales. That’s why they add more salt, more sugar, more artificial colors, and more flavor enhancers. All of these are designed to make food look better, taste better, and trigger a stronger dopamine response in the brain. But these substances are unnatural, unhealthy, and harder for the body to digest compared to whole, natural foods.
If someone struggles with cravings, I believe the best approach is to focus on high-quality, natural foods and eliminate those that don’t serve them well.
That, in my view, is the path to longevity.
Many athletes and non-athletes today rely on cold exposure, ice baths, and sauna therapy. Do you think these methods are key, or are they somewhat overrated?
I think both saunas and cold exposure can be extremely beneficial. Humans naturally have excellent thermoregulation.
These methods can be great for both physical recovery (by constricting and dilating blood vessels) and mental well-being. When you’re in a sauna or cold water, you are essentially meditating, alone with yourself, and it gives you time to mentally reset.
There are also studies confirming that the more frequently you use a sauna, the more you reduce your risk of cardiovascular diseases. That was surprising to me as well.
When it comes to cold exposure, I see its biggest benefit in the psychological aspect. When you step into freezing water, your brain immediately signals: You’re going to die! But in reality, you breathe through it, endure it, and overcome yourself.
Once you step out, your body releases a huge amount of dopamine—apparently even more than after using cocaine. And what’s important is that this dopamine stays elevated for several hours. So, not only do you get an incredible feeling afterward, but you also gain the realization that you conquered it, that you survived, and that you are in control of your body rather than being a slave to impulses or fears.
This strengthens discipline, resilience, and willpower. So, I do think saunas and cold exposure are beneficial.
However, when it comes to longevity, there isn’t clear data proving that these methods significantly extend lifespan.
How do you personally track your progress? Are there specific indicators, beyond appearance and strength, that tell you you're moving in the right direction?
It can be quite difficult to track this on yourself.
As I mentioned earlier, stool quality, skin health, and dental health are great indicators of how your body is doing. However, many of these signs manifest over the long term, and often, people only recognize issues when it’s already too late.
That’s why I recommend regular blood tests—every three to six months—to monitor hormone levels, cholesterol, blood counts, and other key metrics. It’s crucial to look at long-term trends—whether certain values are increasing or decreasing. Blood pressure is also an important indicator.
Overall, long-term analysis is much more insightful than one-off tests, which on their own don’t tell you much.
Now, let’s move into the final part of our interview—mindset and philosophy. If you could give your younger self one piece of advice about training and health, what would it be?
Honestly, everything I’ve done has led me to where I am today, so I wouldn’t change anything major.
I think my journey developed naturally, but fortunately, I realized fairly early on that chasing maximum muscle mass isn’t meaningful.
Luckily, I never got into steroids, and I never fell into the trap of “I want to be as big and muscular as possible.” I realized relatively soon that the healthiest approach is a balanced lifestyle.
Because once you start dedicating yourself to any high-performance sport, it inevitably leads to the deterioration of other areas of life—and fortunately, I recognized this early enough.
We often hear the term "optimal health," but how do you define it? Is it a feeling, a measurable metric, or something deeper?
I’d say it’s a combination of both—how you feel and measurable data.
To me, it’s a balance between mental and physical well-being. You can have perfect blood tests, a great physique, and win competitions, but if your mental health is a mess, you won’t feel healthy. Someone can be in peak physical condition, but if they lack social connection and emotional support, it can lead to serious psychological issues.
On the other hand, someone might feel great about themselves, but if they are morbidly obese and their bloodwork is disastrous, they’re definitely not healthy.
So, optimal health means achieving balance between mental and physical well-being.
Measurable indicators matter—stool quality, dental health, skin health, sleep quality, appetite, energy levels, and, of course, bloodwork—hormone levels, cholesterol, blood sugar, and blood pressure.
You can’t rely only on how you feel, because feelings can be misleading. But at the same time, you can’t rely purely on numbers, because mental well-being is just as important as physical fitness.
Imagine it’s the year 2050. What does an ideal human lifestyle look like in the future, and what does the average one look like?
We’ve touched on this in previous questions.
I think the ideal human lifestyle will be more guided by algorithms—but in a good way.
Just like today we use weather forecasts to decide how to dress, whether to bring an umbrella, or how to plan our day, in the future, people will use real-time health data the same way.
They’ll check their body’s predictions based on data from smartwatches, Oura rings, and various sensors, adjusting their diet, workouts, sleep, and work productivity accordingly. This means they won’t just make decisions based on how they feel at the moment but rather on real biological indicators.
If society embraces this correctly, it could lead to greater longevity and a higher quality of life.
However, I imagine the average lifestyle will look completely different. There will be a group of people who live solely based on impulse—choosing whatever they feel like in the moment without thinking about long-term consequences. They won’t track their body’s health, won’t follow any recommendations, and their lifestyle will lead to a decline in both physical and mental well-being.
I believe people will be split into two extremes. One group will live extremely health-conscious lives, tracking their data, following advanced health predictions, and striving to live as long and as well as possible.
The other group will live on autopilot, guided by emotions, habits, and short-term impulses that ultimately destroy them—but they won’t have the discipline to change.
And I definitely want to be in the first group.
Is there anything else you’d like to share with the listeners and readers?
I think the most important question everyone should ask themselves is:
"What is my purpose in this life?"
"What do I want to do for others?"
Because everything we do is ultimately for someone else. Everyone should have a sense of value they want to contribute to the world. Even if you help just one person, it’s still worth it.
Everyone should ask themselves:
"What is my purpose? What am I good at? What do I enjoy? What can I share with others?"
I believe this is the key to a long, healthy, and fulfilling life. Once you find that purpose, the next step is figuring out how to do it as effectively, as long, and for as many people as possible. That’s where daily rituals, routines, and healthy habits come in—they help you stay productive, endure longer, work efficiently, and bring value to more people.
And that, in my opinion, is the true path to long-term happiness.
