Sports Performance Coaching and Soccer Breathwork

Working with Soccer Pros and Ambitious Academy Players

Most soccer players know they’re capable of more - but feel that pressure, inconsistency, or overthinking is holding them back. My work focuses on training the part most players ignore: how the mind operates under fatigue and pressure and how the nervous system handles stress. Instead of relying on hype, motivation, or surface-level mindset tips, I combine biology-first regulation, practical mental performance tools, and structured training habits so players develop a clear strategy to enter games focused, know proven mindset tools to stay calm and play free in trials and high-stakes games - instead of choking under pressure like I did.

About me

Stefan Peter

Hi, I’m Stefan. I know firsthand how much the inner game influences the outer game because I missed my own chance to go pro. As a teenager, after being scouted by Manchester United in a youth tournament, pressure got the better of me and I learned that talent and hard work alone are not enough if I wanted to go pro.

Today, I help pro football players and those who want to go pro, transform their game from the inside out in 12 weeks — so they can play with pressure confidence, not just in training or on good days. Something I wish I had before my big chance - instead of only relying on positive thinking and visualisation.

Why this works

Elite performance is not random. Players who understand their unique strength, uncover their hidden blocks and learn how to stay in control under pressure build real confidence - confidence that is no longer dependent on results or external factors. This inner growth shows on the pitch, especially in big moments. Coaches and scouts notice it immediately because beyond talent, they look for presence, resilience and mental strength.

1 - Our First Conversation

Our first conversation is about getting to know each other and creating clarity. We’ll talk about your current situation, your goals, and the mental challenges you face in football.

Structured, honest, and no strings attached.

2 - Your Gameplan

After our first call I create your personal 12 week gameplan based on your career goals and current challenges on and off the pitch. Once you know the gameplan I have in mind for you, it's up for you to decide if you want to go into the 12 week transformation or not.

3 - Your Personality Analysis

From coaching day one you’ll have complete clarity how to reach the next level step by step - instead of hoping things get better, or blindly pushing harder and risking injury.

1 - Soccer Breathwork

My mental performance training approach starts with biology first. Specific soccer breathing techniques help to reduce stress, improve recovery and even boost repeated sprint abilty by up to 64%. Scientifically proven methods regulate the autonomic nervous system, improve mytochondria energy production and help you getting out of the constant fight and flight state, when you need to.

2 - Mental Training

Focus and concentration is what follows naturally and the base for mental training, visualization, self talk techniques etc. Cognitive restructuring of the subconscious mind can help to overcome annoying blockages. Only then athletes build real and lasting mental strength and resilience needed for high-pressure situations.

3 - Performance Habits

Creating a longterm vision & setting goals beyond just winning games on the pitch is the final part based on your own motivational drivers and personality type. Together we build your unique high-performance habit protocols, so you can perform and enjoy no matter the circumstances.

Performance Anxiety

Most athlete's nervous system is in constant fight or flight mode. The inner battle never stops and emotional ups and downs can cause overthinking. Breathing is the mirror of your inner state and dramitically influences your abilty to recover during sleep and build mental toughness and resilience.

"Silly" Mistakes

Many players waste 5–7 minutes to get fully focused and locked in at the start of a game. This slow mental start often leads to avoidable "silly" mistakes. With the right mental training and breathwork protocol, focus and concentration can become a powerful advantage and a key driver of your peak performance.

"Gassing Out" too Early

87.5% of athletes breathe dysfunctionally. When your breathing muscles are not fit for high performance they steal oxygen-rich blood from your legs, leaving you feeling heavy, slow, burned out and breathless. You don't just feel tired, your body language also shows tired.

"I used to struggle with performance anxiety, overthinking every mistake, and losing focus in games. It killed my confidence and made me play safe, not smart. Working with Stefan changed everything. Starting with breathwork was a gamechanger and it helped me understand what mental training really is and how I can improve it, how to stay calm under pressure, think clearly, and finally play with more freedom and focus."- Player feedback

Andrew Swift

As a collegiate athlete the mental side of sport is just as difficult as the physical aspect so when Stefan reached out offering his knowledge I took the opportunity. The best thing about Stefan was how personal he was, he delved in about my story before getting into the logistics of psychology. I’ve struggled a lot with recent injuries which takes a big toll of one’s mental health. He helped me identify and overcome difficulties I never knew I had.
