Alexander Technique

Frederick Matthias Alexander failed as an actor because he'd lose his voice as soon as he stepped on stage. So hedeveloped a series of special postural re-education exercises to help him overcome the stress and physical tensions that caused his problem. Other actors were so impressed that they queued to learn his lessons.

Alexander Technique is now used throughout the world, especially by actors, dancers, singers and athletes, to improve their performance. It can also be a great help for sufferers of asthma, back pain, arthritis and many digestive disorders. Practitioners regard themselves as teachers and their clients as pupils. It's important to spend just a few minutes each day practising the techniques you've been taught to get the best results.
