can anybody tell me what exactly it is?

The alexander technique is a relaxation method that we did in drama once. You turn the lights off and slowly breath out your stress from a ball in your stomach out of your mouth.

Alexander Technique is brilliant. It cured me of painful problems I had had for years by teaching me how to use my body properly.

It's awesome. Do it if you get the chance. I learnt soooo much in 6 lessons I used to hurt all the time in my back/shoulders/neck, the pain has completely gone now, I can even do 3 hour orchestral rehersals in crampt spaces with no problems. It's even good value because you do most of the stuff by yourself at home If you've got any questions, do PM me.
