Nice
to have you here!

Hey,
I´m David
glad you’re here.
For over seven years, training has been a central part of my life. What started as a passion has become my mission: helping people become stronger, healthier, and more confident.
With my Bachelor’s degree in Fitness Economics, an A-license as a fitness trainer, and comprehensive further education, I develop training concepts that truly work – well thought-out, evidence-based, and tailored to your individual goals.
My focus is on performance, muscle building, and prevention. This means improving your performance in a targeted way, shaping your body visibly, and preventing injuries and discomfort in the long term.
MY JOURNEY
2014: I started training
2021: I began my studies
2022: I became a self-employed trainer
2025: I founded Performaxx

You,
have the choice!
Personal training means to me:
Individualized, scientifically sound, and effective in the long term. I'll guide you on your journey to your personal goal – with a training concept tailored to your body, your motivation, and your daily routine. Whether your goal is muscle building, injury prevention, or performance enhancement – every program is based on current sports science findings and practical experience.
Muscle Building
Through targeted training planning, progressive overload, and functional strength training, all muscle groups are strengthened. The result: harmonious, stable, and high-performing muscles – visible and tangible.
Injury Prevention
A strong, flexible, and resilient system is the best way to prevent injuries. Functional training, stability exercises, and individually tailored load management help you prevent pain and stay healthy in the long run.
Performance
More strength, endurance, flexibility, and mental fortitude – for everyday life, work, and sports. Performance enhancement here means not only physical progress but also mental resilience, focus, and motivation.

It's
about your team
Choose corporate training: Power for your team, more energy, and a shared experience that fosters connection.
Healthy employees are the foundation of successful companies.
My corporate training combines exercise, motivation, and team spirit – for more energy, less absenteeism, and a sustainable health culture within your company.
Team Building & Motivation
Joint training sessions, team challenges, and reflective feedback rounds promote cohesion, communication, and mutual support – essential factors for a strong, motivated team.
Health & Prevention
Targeted training planning, ergonomic movement coaching, and load management help prevent ailments and improve physical resilience. This reduces absenteeism and strengthens the performance of each individual.
Performance & Focus
Functional training concepts and active breaks promote concentration, regeneration, and mental clarity. This creates productive, healthy, and resilient teams – fit for the challenges of everyday work.
