As an energetic child – inspired by my older, bodybuilding-obsessed cousins – I discovered my enthusiasm for strength training at the age of 14. What started in my parents' garage quickly became a fixed part of my everyday life and led me to the gym at 16, where I trained almost every day.
My advanced-level sports course, my subsequent degree in sports science at Johannes Gutenberg University Mainz and my part-time job as a fitness trainer at Fitness First in Mainz laid the foundation for the path I am on today. Right after graduating, I became self-employed. Since 2015, I have been supporting people as a personal trainer in integrating exercise into their everyday lives.
My own training took me from initial muscle-building training via athletic training and CrossFit to functional training. That, along with numerous further qualifications in functional training, athletic training, strength training, movement analysis, mobility, prevention and nutrition, has shaped my work over the years.
Customized Functional Training grew out of my experience and my knowledge: personal support, scientifically sound and practice-oriented planning. Added to that is a studio of my own, which I designed according to my own ideas and requirements for awesome training.
My sporting career began on the handball court and led me to the gym at the age of 15. What was originally intended as a supplement to team sports quickly developed into a passion that drives me to this day.
In 2019, I moved to Mainz to study sports science at Johannes Gutenberg University Mainz. I successfully completed my master's degree in “Health Promotion and Therapy through Sport” in 2025. Out of interest in therapy and above all in the human body, I began training as a physiotherapist at the University Medical Center Mainz alongside my master's thesis. Hopefully I will be finished with it in 2028.
Even during my studies, I worked in Personal Training and group training at the Sportraum in Mainz. Particularly in one-to-one support, I get to know my clients more closely and accompany them in achieving their various goals. The variety this brings is great fun for me and keeps me motivated. My clients benefit from this drive – a win-win situation.
I have been working at CFT Mainz since May 2025. It is important to me that you feel professionally well looked after and comfortable at the same time. I show you how to move consciously and with control – so that every exercise is spot on. And we have a good time together while we're at it.
My enthusiasm for training was more or less handed to me in the cradle – my dad was a bodybuilder. Through handball and football, my path to a sports degree was ultimately almost predestined.
In 2020, I began my degree in sports science at Johannes Gutenberg University Mainz. At the same time, I gained practical experience as a personal trainer at the Sportraum Mainz and completed my Fitness Trainer A License at the Deutsche Berufsakademie für Sport und Gesundheit. Since team sports have always played an important role for me, my work placement took me to the U23 of 1. FSV Mainz 05 – from individual athletic training to looking after the entire team.
I am currently completing my master's degree in “Health Promotion and Therapy through Sport” and additionally deepening my knowledge with the MTMT method. That is a further training course. In my own training, I bring together strength, endurance and mobility – with high standards and clean technique.
I have been part of the CFT team since November 2025. In training, I don't follow the plan rigidly but focus on you: on your development, how you feel on the day and what is possible right now. That way, every session moves you forward in a meaningful way – even on days when not everything goes smoothly.
As a child, my entry into sports began with football. Strength and athletic training quickly became important building blocks for improving my performance on the field in a targeted way.
Long-lasting back problems later shaped my view of training significantly. I began to question movements, loads and physical interrelationships more closely and thereby found a better way of dealing with my complaints. These experiences were an important reason for my training as a physiotherapist at the Asklepios Bildungszentrum Wiesbaden.
I have been active as a trainer since 2021. At Fitness First, I gained valuable practical experience with people from all kinds of backgrounds and expanded my know-how with the Fitness Trainer A License as well as qualifications in functional training and Personal Training.
My physiotherapy training helps me not to look at movements in isolation. I recognize how joints, muscles and movement patterns interact, and can select or modify exercises precisely accordingly. I use this knowledge so that you move more efficiently and build up your training with clean technique.
Julia is self-employed and works with CFT as an external partner. With us, she is responsible exclusively for nutrition coaching.
For me, exercise, nutrition and well-being are closely linked. That is why I studied sports science at Johannes Gutenberg University Mainz and then completed the master's program “Sport Science – Movement and Wellbeing”. The professional basis of my nutrition coaching is my specialist training as a holistic nutrition coach at the Paracelsus Heilpraktikerschule in Wiesbaden.
In my coaching, I want to get to know and understand your experiences, habits and possibilities with regard to your nutrition. Together we look at what works in your everyday life and where changes can make a meaningful difference. If something doesn't work, it gets adjusted.
It is important to me that you understand your nutrition better and find solutions that can be integrated into your life in the long term.
At 18, I was at a turning point: at 135 kilograms, I initially lacked the drive for strength and endurance training. My brother, an ambitious triathlete at the time, brought me to the gym. The first visible progress changed everything – what had taken effort turned into genuine enthusiasm.
As my fitness grew, so did my interest in training and health. That is why I completed a dual study program in health management at Fitness First. While still working on my thesis, I started working at CFT to support Felix.
Now for the next plot twist: I am passionate about baking pizza. What began as a hobby developed over time into my second professional mainstay. Alongside Personal Training, I founded my own pizza catering business called Pabloo. The irrepressible enthusiasm Felix feels for training and movement is what I feel when baking. When the idea for a shop of my own finally came up, I had to choose between Personal Training and pizza. Building up my business “Slice Club” needs my full attention.
After two and a half years as a personal trainer at CFT, you can now book or visit me as a pizza baker. Maybe one day, between dough, tomato sauce and new recipes, I will get bored and the longing will grow so strong that I return to the CFT studio for a few hours. Until then, you will probably find me wherever a pizza is just coming out of the oven.
Every session follows a clear training structure. Exercises, load and focus areas are prepared to match your goals and your development.
You learn what you are doing and what matters in an exercise or movement. We convey expertise clearly and understandably – not to show off.
Your goals, your starting point, your previous experience and how you feel on the day are taken into account. Questions and feedback are part of your training.
Every session is recorded in your training plan. That way, other trainers can also follow your development and continue your support in a meaningful way.
Training is allowed to be demanding. That doesn't mean the atmosphere has to be tense. Concentration, motivation, conversations and shared laughter go together at CFT.
Right after his studies, Felix becomes self-employed at Fitness First in 2015 with his sole proprietorship “Felix T. – Personal Training”.
During the coronavirus pandemic, Felix creates a functioning training spot at the Drususwall with simple equipment.
Because of cold, rain and darkness, Felix trains from November 2020 until March 2021 sheltered from the weather at the stadium of 1. FSV Mainz 05.
Felix initially trains in the tent at CrossFit Zollhafen; the interim solution turns into a permanent location.
In January 2022, Felix founds CFT Mainz GmbH; the first Personal Training studio is created at CrossFit Zollhafen.
Growing demands on atmosphere and size lead to the move to Mainz Hauptbahnhof in September 2023.
Since January 2024, Simon Teichmann has strengthened CFT as its first employee and supports Felix in Personal Training.
CFT receives the offer for a shell space at Karoline-Stern-Platz and can plan the studio according to its own ideas.
CFT moves to Karoline-Stern-Platz 7, where changing training locations have given way to a boutique studio of its own.
With the new studio, the team grows: Bastian joins in 2025, Paul follows, Alex has strengthened it since 2026.
