Stefan Peter - Personal development for athletes Ever wanted to be as emotionally and mentally strong as the most seasoned pros in the locker room?

The players who step up for a penalty in the 90th minute and look like they do it every day in training.

They're not just mentally stronger than everyone else.

Their nervous system is in a different state.

They learned to control their heart rate before a PK.

Remember CR7 in the last Euros when Whoop tracked his heart rate before PK?

They control their breathing.

They keep their mind clear from distractions.

They keep their body loose instead of tense.

This is a trained physiological state - but most players never get taught how to access it.

Here's what actually happens for most players before big games.

They arrive nervous and think it’s normal and can’t do anything about it.

They say: “it means I care”
….BUT in reality they leave performance on the table because they are not in their optimal performance zone.

Breathing is shallow. Muscles tight. Cortisol high.

Decision-making is slow right from min. 1

They are mentally not in the game.

Their brain and muscles don’t get enough oxygen.

They call it nerves. It's actually their nervous system outside its performance zone.

And here's what most players don't know.

Box Breathing and Wim Hof before a game are not the answer.

Not because they're bad, but because they're not designed for a player about to compete. Wrong tool. Wrong moment.

If you're struggling to stay focused, feel easily irritable/moody, or you wake up drained - even after 8h of sleep - the problem may be your nutrition.

Modern diets are flooded with omega-6-rich oils from processed foods. Especially seedoils like sunflower oil. "Healthy" products are often full of it. Peanut butter, Protein bars, Recovery bars, Granola, Sports snacks but also Restaurant meals and Meal-prep food. I know - it sucks 😢

At the same time, most athletes aren't getting enough omega-3s.

The result? An omega imbalance that many experts believe contributes to chronic inflammation - one of the biggest factor for the development of diseases such as cancer, arthritis , heart diseases but also depression and more.

Omega 3's play a big role in gut and brain health. This is where it's getting interesting for mental performance - because a lack of omega 3 reduces cognitive performance.

You can't expect elite cognitive performance from a brain that isn't properly nourished.

In athletes a deficit can look like:
- Prolonged muscle soreness
- Getting emotionally irritated easily
- Feeling depressed
- Struggling to stay focused
- Feeling low energy despite doing the recovery or sleeping enough

Most athletes not only have a deficiency but also don't know their blood levels.

Ask your doc to check:
1) Ratio between Omega 6 to Omega 3
2) Omega 3 index in %

An optimal ratio is 3:1! Index 8% or higher.

Unfortunately I regularly see test results 30:1 or worse. Recently even 50:1 in a young player who reported feeling tired all the time.

Test don't guess is a principle I live by - so every athlete I work with gets the same recommendation here: Test your omega levels.

If you want my personal recommendation on the omega-3 test my athletes do - send me a DM, happy to share👍

PS - Christiano for sure checks this biomarker frequently 😉

Football and spirituality - why it goes together and how it actually helps pro athletes perform more consistently even under pressure.

Do you practice meditation, breathwork, mindfulness or other "spiritual" practices?

At high altitudes, the biggest challenge for soccer players is that there’s less available oxygen in the air.

That means the respiratory system has to work harder to deliver oxygen to the muscles and brain, especially during repeated sprints, high-intensity transitions, and recovery between efforts. Players often experience elevated breathing rates, faster fatigue, reduced decision-making sharpness, and slower recovery during the match.

From a breathwork perspective, many athletes also unconsciously over-breathe under this kind of stress, which can further reduce CO₂ in the blood and make oxygen delivery less efficient.

So on top of less oxygen in the air
You also reduce the uptake from the blood to brain and muscle. It's a viscious cycle.

This is why players can feel “gassed” much earlier at altitude, even when they’re very fit.

Specific breathwork training - like the Oxygen Advantage methods I use with my athletes - can help prepare the body for these conditions by improving breathing efficiency, CO₂ tolerance, nervous system regulation, and recovery capacity.

With targeted respiratory training, athletes can adapt better to oxygen-demanding environments and maintain composure and performance for longer periods at altitude.

One of the hardest things for talented football players is when...

You finally get your chance.

Preseason starts.
The coach calls you up with the first team.
You know you deserve to be there.
You’ve put in the work for years.
You have the talent.
You’re fit.
You’re hungry.

And then… something happens.

You stop playing freely.

Your touch feels heavier.
You overthink simple decisions.
Your legs feel tight.
You hesitate instead of reacting.
You play “safe” instead of playing like YOU.

Meanwhile, in training, you know exactly what level you’re capable of.

Most players think this means:
“I’m not mentally strong enough.”

But what holds players back under pressure is usually not what they think it is.

People say “the mind” controls performance under pressure.

Not exactly - not only:

It’s your nervous system.
It’s your subconscious patterns.
It’s your breathing.
It’s your internal stress response.
It’s the hidden processes you’re not even aware of.

When your nervous system perceives pressure as danger, your body changes instantly:
• breathing becomes inefficient
• tension increases
• decision-making is off
• oxygen and nutrient delivery to the brain is less
• composure disappears

And suddenly the player who looks world class in training cannot show his real level when it matters most.

This is what I help players transform in 12 weeks.

Not by “motivating” them.
But by training the hidden systems behind confidence, composure under stress, recovery and performance under pressure.

Because confidence is psychological and physiological. ➡️ Biology beats mindset

If you want to play free, confident, and closer to your full potential when opportunities come — follow along.

And share this with a player who needs to hear that struggling under pressure is not simply a lack of mentality or talent - it's also biology!

Erling Haaland doesn’t just train his legs. He trains his breathing system.

And since is what I do let me explain why this makes him a better player.

Erling regularly does hard intervals on the erg bike inside a hypoxic chamber simulating high altitude at + 40°C heat.

Why?

Because elite performance is not only about muscles or VO2 max. It’s also about how efficiently your body handles Co2 - and we elite sports science starts to take this into account more and more.

Most players believe their legs burn because they are not fit enough - and they believe bad decision making under pressure only needs more reps to fix it.

But let me tell you this. It can be untrained breathing and weak breathing muscles that actually create these problems for you. That's why Haaland trains it.

Athletes with a trained breathing system that matches the rest of their abilities stay calm under pressure, recover quicker between sprints, and can maintain speed deeper into the game.

Better CO2 tolerance = better oxygen delivery to muscles, better nervous system control, and less wasted energy.

This is one of the hidden reasons some players look “unfatigable.”

The altitude simulation increases respiratory demand. The heat adds stress. The intervals force adaptation. But the key is HOW and WHEN you integrate it.

Done wrong, it can fry the nervous system.
Done right, it can completely change endurance, recovery, focus, and composure under pressure.

And this is only one piece.

Specific breathing work can also help football players:
• recover faster after intense runs
• improve sprint repeatability
• increase focus under pressure
• improve sleep and recovery
• regulate pre-game nerves
• sharpen decision making late in matches

Breathing is not just recovery anymore.
At the highest level, it’s performance training.

Cristiano Ronaldo prepares for matches like a military operation, not just physically, but psychologically.

These is his 3 step mental warmup you don't get to see:

1️⃣ Before games, Ronaldo focuses heavily on visualization. He mentally rehearses key moments: scoring, making runs, beating defenders, even taking penalties. Sports psychology research shows visualization activates many of the same neural pathways as real performance, helping reactions feel faster and more automatic under pressure.

2️⃣ He’s also obsessive about controlling stress and recovery. Ronaldo prioritizes sleep, naps, hydration, structured routines, and calm pre-match focus routines like breathing exercises. Because anxiety and fatigue impair reaction time, decision-making, and muscle coordination.

3️⃣ Teammates and coaches have described him entering an intense “locked-in” mental state before kickoff — music on, distractions off, total focus. He has also reportedly used meditation, breathwork and mindfulness techniques when feeling stressed before big games.

Under the stadium lights, before the roar of 70,000 fans… the real battle starts inside the nervous system.

Šeško knows this - so this is what he does....

Heart racing. Muscles tight. Thoughts everywhere. Most players know this feeling very well.

What can we do?

Science shows controlled breathing can directly influence the autonomic nervous system — the system controlling stress, focus, heart rate, and oxygen delivery. Slow, intentional breathing lowers excess cortisol and adrenaline, helping players shift from panic mode into controlled aggression. The result? Sharper decisions, calmer reactions, and better composure under pressure.

And it’s not just mental.

Breathing mechanics affect carbon dioxide balance in the blood. Most players think “more breathing = more oxygen.” Wrong. Overbreathing actually causes CO₂ to drop too low, making it harder for oxygen to unload into muscles and the brain through the Bohr Effect. That’s why anxious athletes can feel dizzy, tight, or mentally foggy even while breathing heavily.

Proper breathwork restores balance.

More efficient oxygen delivery. Better blood flow to the brain. Lower heart rate. Improved reaction speed. Reduced muscle tension. Greater endurance under pressure.

Even elite footballers use it. Benjamin Šeško has spoken about using box breathing before matches — inhaling, holding, exhaling, holding in equal counts — to regulate nerves and lock into focus.

But here’s what most people miss:

Box breathing is not magic.

And many athletes do it completely wrong.

Some breathe too aggressively. Some force huge inhales. Others hold tension in the chest and shoulders. Instead of calming the nervous system, they accidentally stress it more. Breathwork only works when the rhythm matches the state you want to create.

A striker needing explosive intensity may need different breathing than a goalkeeper trying to stay ice-cold.

Many players don’t struggle because they lack ability.

They struggle because after one mistake, the mind takes over.

❌ Overthinking.
❌ Frustration.
❌ Fear of making another mistake.
❌ Losing confidence during the game.

Do you know this?
Truth is:
over-analyzing every action kills performance quicker than Manuel Neuer can lift his offside arm. 😅

After training → reflection is important.
During competition → too much self-monitoring interferes with flow.

This is often described as:
👉 Self 1 = instinct, flow, automatic ex*****on
👉 Self 2 = ego, analysis, control, overthinking

Top performers don’t remove Self 2.
They just know when to let go of it.

Robert Lewandowski says the mental part is 70% of his top performance.

A big part of mental training is learning how to reset quickly after mistakes, regulate emotions, stay focused under pressure and analyze mistakes without getting emotionally stuck in them.

Because performance is never only about football.

Stress in relationships, pressure at home, financial stress, fear of failure… all of it affects the nervous system and the nervous system affects performance.

✅ That’s why my approach to mental training starts with the inner systems that block performance the most.
