F. M. Alexander's technique to heal without medical aid, but by the correct use of posture and movement, has a worldwide following, and has done ever since it was first pioneered over a century ago. The Alexander Principle is a method of mind and body re-education that reduces stress and muscle tension and revitalises all who practise it. Dr Wilfred Barlow studied under F. M. Alexander himself, and this pioneering book, The Alexander Principle, is now a classic. Recently updated, it is essential reading for everyone interested in the technique.
