Tablework is a part of most Alexander Technique lessons.  The idea behind constructive rest is to give the student a chance to experience and learn the principles of the Alexander Technique while there are less demands on the body.

During this time you lie on your back with support under your head, and in your normal attire, on a bodywork table.

Alexander teachers use a light and highly-skilled touch that is not manipulative or intrusive but rather trained to heighten you kinesthetic experience. While on the table the teacher will gently move you and help guide you into a release of excess muscular effort and into greater integration.

The table lesson is very relaxing for most people, but it is not a passive experience, it is a time to heighten your thinking and develop your skill in the Technique.
