The Alexander Technique, Feldenkrais Method, and Yoga are three related modalities. They all integrate the mental, emotional, and physical intelligence that allows an integrative balance within ourselves. The larger umbrella that they are covered under is called Psychophysical Re-education or Somatic Education.
Alexander Technique is a learning method that teaches improved posture and movement, which helps reduce stress, stage fright, and prevent problems caused by unhelpful habits. During a number of lessons, you're taught to be more aware of your body, how to improve poor posture and move more efficiently.
Feldenkrais Method is a type of exercise therapy that uses gentle, mindful movement to bring new awareness into every aspect of your life. The method reorganizes connections between the brain and body and so improves body movement and psychological state allowing a new way of thinking.
Yoga is a gentle way to improve your posture, balance, and coordination. Yoga is a systematic practice of physical exercise, breath control, relaxation, diet control, and meditation aimed at developing harmony in the body, mind, and environment. We use the term Viniyoga—an ancient Sanskrit term that implies differentiation, adaptation, and appropriate application—to refer to our approach that adapts yoga practice to the unique conditions, needs, and interests of each individual.
