B-Sthenos is a Brussels-based calisthenics association born from a shared passion — for movement, community, and purpose. Founded in 2020 and registered as ASBL in 2021, we bring together athletes and coaches around structured training, mutual growth, and European-scale social projects.
Our spirit animal is the Nahual — the shapeshifter of Mesoamerican tradition. It guides our philosophy: strength that transforms, discipline that liberates.
