This is a fun, creative and empowering journey into a fresh way to approach your yoga, and get twice the strength/stretch benefits from every pose.

Most yoga classes are too hard on the joints and don’t incorporate anatomy enough to keep you properly safe. In these classer you are offered new tools and techniques, and organic, fluid movement that can free you from pain and strain, and build more flexible strength in far less time!

Sadie offers modifications and variations for most levels and limitations—if you’re a strong Beginner, Intermediate or Advanced student or teacher of yoga, even if you have joints you need to be careful of…you can do this!
