One-On-One Session
If you are dealing with physical tension, specific complaints, injuries, or stress, private sessions can offer the personal attention you need. Together we look at your posture, movement patterns, and areas of tension, and work step by step towards more space, ease, and awareness in the body. I offer one-on-one Critical Alignment Yoga sessions in Amsterdam. I teach in Dutch, English & Spanish.

Good alignment allows the body to move freely without tension. However, due to unconscious habitual postures, the upper back can become crooked, shoulders stiff, and the lower back tense and sensitive. This disrupts the free passage of movement, leading to discomfort and strain.
With Critical Alignment Yoga, you become aware of these tension patterns and learn to transform them into relaxation and strength. Using specialized CAY tools, you’ll discover where tension resides in your body and how to release it for greater ease and balance.

Almost everyone experiences an injury at some point in their life. These injuries are caused by, for example, due to an accident, or they can build up slowly, such as ‘repetitive strain injuries’ (RSI), which are common in work environments. In addition to our body, we can also experience psychological stress and tension, which can amplify the effect of emotional instability and can lead to fear, burnout, and other mental and physical health problems.
Critical Alignment Therapy (CAT) sheds new light on complaints in the spinal column and related complaints. CAT is a method with a new form of anatomy based on bone connections that come about through relaxation. This creates a cohesion that uses so-called reflex forces, organized by posture muscles.

I-Flow instead of holding poses statically, practitioners flow through a choreographed sequence that aligns with the rhythm, length, and emotion of a song, aria or instrumental piece of music.
I-Flow is where movement, breath & melody converge in choreographic harmony, blending Ballet and Yoga Asanas with music and continuous movement. In this class, we weave through sequences choreographed to rhythms; you’ll flow, breathe, and move as one, guided by melodic beats and alignment precision.

Move with more freedom. Feel at home in your body again!
Do you often feel discomfort or pain in your neck, shoulders or lower back?
You are not alone! Stress, tension or poor posture makes your body feel stiff, heavy and restricted.
My upcoming online programs are designed to help you practise regularly at home, in your own time, with clear guidance and personal support. Step by step, you will learn how to release deep tension, restore mobility, improve posture and build strength from within.
These programs are ideal if you want a structured practice but no longer want, or are no longer able, to commit to an expensive yoga studio or gym membership.
Through the Critical Alignment method, you will learn how to work with your body in a precise, calm and intelligent way. The aim is not only to reduce physical tension, but also to create more ease, energy and freedom in your daily movement.
As your body begins to move freely, your mind can soften too. Regular practice supports not only your physical wellbeing, but also your mental and emotional balance!

After finishing my professional dance career I was desperately looking for ways to keep my body moving and stay injury free. Following private classes with Iris has saved me. She is attentive, caring and a powerful coach. Highly recommended!

De lessen van Iris Reyes zijn van een bijzonder hoog niveau. Zij weet op een bijna medisch-wetenschappelijke manier begrijpelijk uit te leggen hoe het lijf werkt, zodat je je bewust wordt tijdens de oefeningen wat zij bedoelt. Deze bewustwording is blijvend is mijn ervaring, ik begin nu te voelen wanneer mijn houding niet goed is. Het is een voorrecht les te krijgen van Iris!
Adriana de Boer
Erg fijne opbouw van de lessen met een duidelijk einddoel. Je weet dus waar je naar toewerkt. Mijn lagerugpijn en pijn in de liezen is helemaal verdwenen sinds ik deze CAY-lessen volg! Iris is een, zeer ervaren docent die weet wat ze doet en dit goed kan overbrengen.

Sinds ik CAY doe ben ik me bewust van mijn houding en heb ik geen rugpijn meer. Het fijne van de online lessen is dat je het makkelijk in je routine kunt inbouwen. De instructies van Iris leiden je heel goed door de houdingen heen en tussendoor vertelt ze ook wat er gebeurt met je spieren en gewrichten.

Iris is an amazing teacher. I have experience to compare… once you start exercising with her you can’t stop yoga, while stop searching for something new. She is simply best yoga teacher and a wonderful human. Our classes are always different, Iris is very thoughtful and creative. As a teacher she is very attentive to even minimal detail, always develop, inspire and push you to perfection. Iris’s classes are highly professional but also very personal, as she cares for every student. I can’t recommend her classes highly enough! Just try and it will change your life. P.S. I have passed 2 surgeries on L5S1 hernia and suffered a lot with post surgery pains and muscles tension. Critical Alignment Yoga was the only thing that really helped me.

Ik volg de lessen van Iris al meer dan 1,5 jaar online waaronder een week in Portugal. De week Portugal heeft mij echt laten ervaren wat Critical Alignment is en met je doet. Het is heel andere yoga dan ik gewend ben, maar voelt als veel diepgaander en helend. Iris geeft erg goed les, vind ik. Ze weet ook online je houding in de gaten te houden en te corrigeren. Ze is zeer professioneel en weet heel goed wat elke oefening met je lichaam doet. Ik kan haar van harte aanbevelen als een krachtige professional die met haar Critical Alignment yoga kan bijdragen aan het optimaliseren van jouw gezondheid.
