Terms & Conditions

Living longer, staying stronger - a forty year discovery of the body’s potential
Ts & Cs

Start times:

All start times are given as local time in Amsterdam (CET).

Please arrive in good time for an in-person class.  You need several minutes to set up your mat and equipment.

Zoom - for most classes the teacher will open the call up to 15 minutes before the hour to give time to address technical issues, and to allow you to check your space for camera angles, etc.  


Health information:

Please inform our teachers if you are injured, have a chronic condition or any limitation.  We will try to offer alternatives to exercises that exacerbate problem areas, sometimes this will not be possible, or may be best addressed through a private session.  We may make note of this information, we will not share this information, however sometimes instructions in class may lead to some indirect disclosure of your issues to the group.



Payments are non-refundable and non-transferable except by special, individual arrangement.


Missed classes:

If you are unable to attend your usual class (Zoom or in person), please notify us, so we don’t worry.

You may be able to make up missed classes, please contact us to find out if we have spaces in other classes.  You cannot make up missed classes from another semester/quarter.


Subscription types:

Mat classes - usually by semester/quarter.  One class a week at the same time/place, or two classes per week.  When in-person teaching is possible, we also offer ‘Mat Plus’, a discounted price on private classes when pre-purchased at the beginning of the semester in conjunction with a mat.  This special price is only available for pre-purchase, and cannot be added to a semester’s mat subscription retrospectively.



Most of our communication is by WhatsApp group.  Your teacher will warn you of any changes to location or time via WhatsApp.  If you do not use WhatsApp, we will try to contact you via mobile or email, but it may not be as timely.


Data handling:

Please see our page for details.

In short - we only use your data for communication relevant to our classes, we will store your personal details in class lists, or on mobile phones.  We do not sell on, or share your data with other businesses.
