www.feldenkrais.com, It's hard to put into words what I do. It's much easier to feel the difference by taking an Awareness Through Movement (ATM) lesson or have a Functional Integration (FI) lesson. These are lessons, not per se classes like regular exercise classes. They are lessons by the simple nature of when you finish the ATM or FI, you have learned something about yourself from the inside out, not because the Practitioner told you. You become your own best teacher, your own best friend, and a more flexible minded adult....along with way too many other great things to mention here.
