thoughts on finding a teacher.....
as with many things, personal recommendation is usually best.
If that's not possible, then how do you find a teacher?
Where yoga classes are concerned, I'm a realist. I get huge compliments from my students and loads of referrals, but I know for most people the main concerns are : is there a class on a day to suit me, at a time to suit me, and in a location convenient for me?
Yet yoga as a field is very broad, and different 'types' can vary a lot.
Unfortunately some schools exist that can 'qualify' a teacher over a two week holiday, with some self certification thrown in. Government legislation is being prepared to combat this (in many fields, not just yoga), in the UK this means organisations will have to be approved by OFQUAL in order to become accrediting organisations, awarding bodies.
At the time of writing there are only two yoga schools in the UK doing this. One is the Iyengar Yoga Association (IYA UK) and the other the British Wheel of Yoga (BWY). So, why not try classes with teachers from these schools? It is the only way to ensure quality and thorough training. They offer two different approaches. So you could try both and see which you prefer.
Personally I am a big fan of the Iyengar method. It offers something for everyone, and teachers are trained to modify poses to suit individuals. No two classes are the same, and its systematic progressive approach is extremely effective.
