What People Are Saying:

Loved how the video course and book flowed together. So many cool techniques with step-by-step demonstration video and extra tidbits along the way. Video is excellent. Loved how you integrated years of wisdom with signs and symptoms to be aware of in this area of the body, like trauma and emotion. So important and easy to lose sight of possible emotional impact when trying to get the physical technique concepts. Your super responsive techniques of muscle swimming, contract release with breathing, and stretches were well received by my practice clients. We saw change after one technique, and there are so many new ways to correct alignments! This course did not disappoint but exceeded my expectations!

ANGELA COMSTOCK

I was extremely impressed with the knowledge and techniques taught in Peggy Lamb’s “Releasing the Iliopsoas and Quadratus Lumborum” course. I’ve been able to successfully incorporate these techniques into my practice; and my clients are happy with the outcomes.

“The pelvis and specifically the psoas muscle is a tricky muscle to work with and is often times misunderstood by the medical field. Peggy Lamb’s massage and release techniques for the psoas helped me save my patient from getting an unnecessary hysterectomy. Thanks Peggy!”

Tish Sisamis; CAPP- Pelvic PT

"I learned much more with a home study format than I typically do when taking live classes. Love the book!"

Lynnda Weaver, LMT, Texas

“I learned how to work on the quadratus lumborum at a physical therapy office, but your info helped me so much more! Never realized all the different directions of the fibers. The spiral motioning to get to the psoas is priceless! Thank you.” –
