About us

More than a box

Your community box on Borsigallee: over 400 m² for CrossFit, HYROX and more – with coaching for every level. Plus café, coworking and physio under one roof.

CrossFit training at MainBox Frankfurt

Training & space

Our training space is designed for performance, focus, and flow. With a 300 m² class area and an additional 120 m² open gym, there is ample room for coached sessions as well as individual training.

The hall features modern, high-quality equipment, a rig with ten full squat stations, rings, and rope climbs, supporting everything from strength work to gymnastics and conditioning. With ceiling heights of up to 5 meters, the space feels open, powerful, and purpose-built for functional training.
