trial lesson




Stichting Stapel provides partner acrobatics. In contrast with aerial acrobatics, the moves are built up from the ground: human structures in balance. It’s not just the end position that counts – getting up and down is just as exciting.

It’s amazing to watch but even more fun to do yourself. The possibilities are almost endless; think about all body parts you can use to balance on each another – hands, feet, shoulders, knees, head!

Acrobatics stands or falls by co-operation. There are basic shapes which require all the principles of acrobatics. Balancing, climbing, jumping, throwing, catching – exploring together how to utilise the position and momentum of each other in order to minimise the amount of strength needed. Trust and safety are always at the forefront.

You work with contrasts: tensing – relaxing, travelling – breaking, moving – standing still. You develop body control whereby co-ordination, concentration and understanding are of great importance.
You develop a technique to carry lighter, fly higher and land with greater control.

In the acrobatics lessons we work on your sense of balance, (directed) strength and body consciousness. You develop these as you go along, so you don’t need to be especially strong, agile or trained to begin doing acrobatics.

Lessons are given by two instructors – one for the ‘under’ and one for the ‘upper’ position: the base and the flyer.

About stichting Stapel

In 1991 Stichting Stapel (Stapel Foundation) was set up by set up by two enthusiastic acrobats who loved teaching and playing with acrobatics.
Stapel wants to stimulate partner acrobatics in all its forms.

Acrobatics lessons form the dynamic core of Stapel.
Participants from the age of 16 can grow from absolute beginner to highly experienced acrobat.
Every spring we put on a festive presentation evening so all participants can show their acrobatic skills.

Stapel has produced the acrobatics shows ‘Licht & Romig’ (Light & Creamy) and ‘De Sterren van de Hemel’ (Stars of Heaven).
The children’s shows ‘Schik met Schrik’ (Fun with Fear) en ‘Rare Haren’ (Crazy Hair) have played for years across the whole country.

Stapel offers advice and coaching for acrobatics shows.
On request, Stapel can set up acrobatic projects for (high) schools and training courses, various companies and organisations, for festivals and parties.

The foundation has cooperated in the development of a curriculum for acrobatics education and acrobatic teaching methods. The foundation also contributes to the Dutch umbrella organisation for acrobatics, Stichting NAF (NAF foundation).

Stapel is the source of information and advice for partner acrobatics in Amsterdam and the surrounding areas.

Course presentations

Acro balance is not only fun to do, but also exiting to watch. In the spring course we use a few lessons to create short acrobatics shows.
These shows are presented to the audience (friends, family, …).

The last course presentation was in 2019 at the Cygnusgymnasium in Amsterdam.

Subsequently there was a buffet with home made dishes by the participants and room for chatting and enjoying a cheerful evening.

Det Rijven & Cahit Metin (Monday lessons)
Det Rijven/Angela Dirven & guest teacher (Tuesday lessons)

The advanced lessons on the Tuesday evening are thematic, and are given in blocks of 4-5 lessons, each block with a different guest teacher.

During the spring course a course presentation is given in which the participants showcase their acrobatic achievements to the public, all wrapped up in a theatrical theme.

Trial Lesson

Anyone who is curious about or interested in doing acrobatics at Stapel can come for a trial lesson.
The best opportunity is the first lesson at the beginning of a new course. This trial lesson is free and if you like you can immediately continue with the full course.
You can also come for a test run on another night, but then it costs € 15 / € 17 (very advanced group).

After the trial lesson you can of course decide straight away if you want to join, or you can think about it for a couple of days. But by the next lesson Stapel would like to know your decision.
If you decide to join the course, the payment for your trial lesson will be deducted from the course fee.

    Stapel aims to make acrobatics accessible for everyone and to maintain high standards by having two paid teachers (a ‘flyer’ and a ‘base’). We are supported by ‘Friends of Stapel’ who donate regularly. As acrobat you can also contribute: If you can afford it, you are welcome to pay more than the minimum amount. In that way we can keep the courses affordable. For this, Stapel is of course eternally grateful!


    By participating in Stichting Stapel classes, participants agree to the following rules:

    Newcomers can follow a trial lesson (in the first week of a course this is for free; afterwards it costs €15 (€17 for the most advanced)).
    Within a week after this class the newcomer decides whether he/she wants to join the course.

    Participants register for a complete course. Aside from the trial lesson it is not possible to participate per class, apart from exceptional cases and incidentally when the participant lives abroad and at the discretion of Stichting Stapel.

    An ‘old’ course member reports no later than in the first week of the upcoming course if he/she doesn’t want to continue the classes; otherwise Stichting Stapel supposes he/she will join in the new course.

    For the very advanced classes it’s only possible to subscribe with a partner, in consultation with the main teacher.

    A course member must pay the course fee in the week he/she starts the course. Good reasons for paying in instalments can be discussed.

    A reduction of 40% for the 2nd course is given, for participants taking part in two courses in the same period.

    Course fees are not reimbursed. This applies, irrespective of the reason for stopping participation (illness, injury, pregnancy, moving house, etc.)

    Classes missed can be compensated in a lower group during the ongoing course or the next course, provided course fees have been paid. Unfortunately compensation is not possible for the basic group as there is no lower or parallel course.

    Video recordings and/or photography of (parts of) classes are not allowed, except of the participant him/herself and their partner(s) if clearly agreed upon.

    Participation in the courses of Stichting Stapel is at one’s own risk.

    Corona rules

    • Work in the same group during the lesson
    • If you spot or join another group check if that's OK with both groups

    And finally ...
    The rules will be modified as needed

    Special workshops

    In addition to the regular Monday and Tuesday acrobatics classes, Det Rijven also gives special workshops with one of the regular guest teachers.

    These are workshops for companies and organizations that want to get acquainted with partner acrobatics, often to relate to colleagues with a different approach. These workshops are about skills such as trust and cooperation, but also about challenges and crossing boundaries. The workshops are developed in consultation with the client.

    Acrobatics workshops at foreign acrobatics conventions and weekends are provided by Det together with Jim Klinkhamer; at the domestic festivals she works with several guest teachers from Stapel.

    Technical lessons or daily training in a week (end) program are also part of the practice of Stichting Stapel.

    Teachers Training Partner-Acrobatics

    by Det Rijven & Jim Klinkhamer

    In 2014 and 2016/2017, Det & Jim taught a series of training sessions for (future) acrobatics instructors. The trainings are in six sessions, spread across three weekends, and include skills such as advanced technical knowledge, analysis of difficulties with the techniques, structuring lessons and explaining tricks.

    The sessions are adjusted to the personal level of experience.

    If you would like to receive information when a new series of these trainings will be organized, please let us know via this e-mail-link.
