No excuses. No giving up. No limits.
Who we are
Ultreia Boxing - More than just a sport, a movement
The name Ultreia Boxing is derived from the old pilgrim’s greeting “Ultreia”, which means “Go further, beyond yourself”. Inspired by the unwavering determination of the pilgrims on the Way of St. James, who walk their path without perfection or planning, but with unstoppable will, Ultreia Boxing embodies the same philosophy: just start and grow. Physically, mentally and beyond!
No giving up. No excuses. No limits.
Our vision is to create a strong community through boxing. Not just in a sporting sense, but in all areas of life. Whether in the ring, in everyday life or in business: Ultreia Boxing stands for the power to always go further and get the best out of yourself.
It’s not about starting perfectly or being perfect. It’s about keeping moving, continuously improving and developing in every way.
- Determination: We believe in the power of unstoppable willpower to achieve any goal.
- Community: At Ultreia Boxing we foster a supportive and motivating environment for all.
- Growth: Continuous improvement - physically, mentally and personally - is at the heart of our philosophy.
- Resilience: We learn how to overcome setbacks and come back stronger, no matter what area of life.
- Accessibility: Everyone is welcome, regardless of fitness level or experience. Just get started!
- Inspiration: We inspire each other to get the best out of ourselves and reach new heights.
