Hyrox

One format, endlessly challenging

Hyrox is running mixed with strength stations, like pushing sleds, rowing and wall balls. The format stays the same, but you set the bar as high as you like. That is why a beginner trains right next to a seasoned athlete in the same class.

We are a certified Hyrox training location. You learn the technique properly and build your fitness step by step.
