A body worker is a therapist who works with the body very often by physically manipulating the body, but he can also give you breathing exercises and work with the energy fields surrounding the body.
There exist many types of body workers and common for all of them is that they work on a physical level to create connection and balance between body and mind, strengthen the energies in and around the body and improve posture.
Examples of manipulative bodywork are massage, chiropractic, structural integration, kinesiology and shiatsu. Examples of non-touch bodywork are reiki, yoga, qui gong and tai-chi.
