The Alexander Technique does not teach position. It teaches proper co-ordination in all normal positions. If the little extension of the spine that Alexander demanded is operative then it matters little what position the body adopts. That is not to say that positions have no importance. There are some positions in which proper co-ordination is difficult or impossible. For instance, it is difficult for anyone to sit in many so-called “easy” chairs without collapsing their spines. These chairs are much too long in the seat to enable anyone without the longest of legs to get support for more than just a portion of his back. Such chairs should be avoided.
