The partners of CrossFit MainBox: Berkin, Johanna and Chris

Welcome to your second home

We are Berkin, Johanna and Chris – as partners we built CrossFit MainBox. To us it is more than a gym: a second home, where a real community welcomes you.

Just come by – no matter where you are on your fitness journey. Whether it is your very first session or you have trained for years: you belong here. Train with us.
