I have attended Stefanie’s MSA training last year and can highly recommend her program. I had little experience with resistance work or the MSA strap before, but the idea of improving my technique, alignment, movement, strength, mobility, and breath sounded amazing. The first few modules covered the theory behind resistance work and the science of stretching. The next few modules covered the practical application of the MSA strap. We learned how to use the strap to strengthen and lengthen different muscle groups. We also learned how to add functional exercises into any movement class. The MSA strap has become such a valuable tool for both my teaching and my personal practice. If you are a yoga teacher, physio, fitness trainer, or just love movement, I highly recommend taking this course. It is registered as a YACEP Program, it is informative, well structured and very inspiring. And Stefanie is definitely one of the best in this field.
