No book or video would be of much help.
What about spending a week somewhere near an Alexander teacher who could see you every day? Perhaps when you go on holiday — or on a business trip?
This is, actually, the best way to learn the Alexander Technique.
Robert Rickover offers 3 excellent suggestions:–
I only plan to make a few comments here, so do read Robert's page first. (The relevant bit is near the bottom of that page).
I totally agree with Robert that a short, concentrated, course of daily lessons is the very best way to learn. The enforced break is also excellent. It gives you time to get used to your new understanding. When you can get back to a teacher again, you will gain from having had time to digest what you learned.
I explain why here: “How long should an Alexander Technique lesson be? How many should I have and how frequent should they be?”.
So, if the course is good enough, your first two options are very equivalent: a residential course that includes a full individual lesson every day can be excellent. You may even find that choice more fun than private lessons — but more expensive too.
If you don't get a full individual lesson each day, you will not be getting the personal attention you need. Such courses are fine as introductions to the Alexander Technique, but no substitute for private lessons.
Check that your daily individual time-slot will be at least half an hour — every day.
If you think I am over-stating the case, then read this cautionary note.
Enjoy your lessons. Best of all, enjoy your new-found freedom.
