Flexors

This is a "core" lesson in many senses! This kind of lesson is usually one of the earliest lessons in an introductory series. It's full of the paradoxical approach of Feldenkrais--free the extensors for more effective action by moving in the direction of flexing; "strengthen" the flexors by making more effective use of your back moving backwards (lengthening the extensors); and pay attention to the "vegetative processes" (e.g. breathing) as you go!
