Frequently Asked Questions

Self-optimisation encompasses all efforts that lead us to experience a greater sense of presence, flow, connection, vitality, and joy.

The traditional approach of the wellness industry often labels individuals as 'broken' or 'needing to be fixed', which can be disempowering. Therefore, our mission centres on optimisation. Rather than focusing on 'fixing' or 'curing', we believe in learning to optimise how our physical, mental, and emotional systems can work together even better.

We are located on Prinsengracht 581, 1016 HT, Amsterdam.
Please note that we also have a separate retail-only location at Keizersgracht 508. Make sure to double-check directions on Google Maps before visiting to ensure you arrive at the correct location.

Our opening hours depend on the day and our class schedule.
