Alexander work is based on the principle of prevention. Alexander would often say that if we are able to stop all the wrong uses which we have built up through habit, then the 'right thing' would look after itself. The goal in learning the Technique is to gradually build up an ability to say no to the old habit pattern which has become ingrained, and instead allow for a more appropriate type of use, which includes an integrated relationship of head, neck and back, dynamically engaged with the arms and legs.

The teacher uses gentle manipulation with the hands, together with words of guidance to help point out and oppose the student's habitual patterns of use and release unnecessary tension. A particular quality of muscle tone is encouraged, allowing the body to become better aligned and balanced. The experience of this is very subtle and is demonstrated repeatedly by the teacher throughout lessons, and in the process, the student starts to build up a new manner of using themselves, together with a greater sense of self-awareness.

Lessons are usually taught privately on a one to one basis, lasting about 45 minutes or so. No special clothing is required. A few lessons can make a difference, and to develop an ability to practice the technique more independently, a course of around 20 lessons or so is often recommended as a foundation.
