Calmness and Flow Summer School
Join us from August 8–10 in Amsterdam for a special Summer School focused on Critical Alignment Yoga (CAY).
Programma
CAY was developed in Amsterdam in the 1990s, emerging in response to the rise of internet culture. As we began spending more time behind screens—browsing, emailing, and later scrolling social media—many of us started suffering from physical complaints like tension in the shoulders, arms, and hands. Alongside this, our mental stress increased.
Critical Alignment Yoga offers a powerful answer to these modern-day issues. It focuses on improving posture in the neck, back, and shoulders, while helping you reconnect with your inner strength. By combining physical release with mental relaxation, CAY is a complete exercise method.
Whether you’re new to CAY or have been practicing for a while, this retreat offers a meaningful experience for all levels—laying a strong foundation for beginners and providing deeper insights for more experienced practitioners.
We invite you to a weekend retreat in our beautiful Amsterdam studio to experience the calmness and flow based on CAY.
