We invite you to join us — certify in Anatomy Trains Structural Integration.

Since its first appearance in 2001, Anatomy Trains has been translated into 12 languages, which has led to Anatomy Trains workshops taught around the world. We are touched and encouraged by the support Anatomy Trains has received from a wide variety of health and movement professionals.

We’re pleased to announce our new core certification program: Anatomy Trains Structural Integration (ATSI – formerly known as KMI). Our ATSI program is based on my development of Ida Rolf’s pioneering work, progressed for the electronic age.

Our new format allows two pathways towards professional certification — our traditional intensive program, or through a series of short workshops coupled with online learning. Everybody needs to start with the Anatomy Trains Structure and Function 3-day overview class — where we get to know you and you get to know us. Follow up with our six regional anatomy workshops in your area or come to our 15-day intensive.

Structural Integration Training

Tom MyersIn the second phase, students apply the assessments and techniques from Part 1 to practice a 3-series protocol of Structural Integration with clinical practice on outside models in a 10-day program.

The third phase, 3 x 10-day classes in as many months, is where students are taught and tested in the full 12-series program of Structural Integration. Graduates from this program are certified to practice ATSI and join the International Association of Structural Integrators (IASI).

All along the way, you’ll get ‘hands on’ personal attention, academic and touch-skills assessments, and all the materials and skills you need to become successful in the practice of restoring natural balance and fluid movement.

Testimonials From Our Graduates

Ryan Glatt

ATSI has been a powerful educational experience that has changed my life, my career, and the functional and structural outcome of all my clients. It's curriculum is essential in complementing other manual and movement interventions, and is the missing link in bringing the experience of touch with groundbreaking science.
