How can the Alexander Technique help my golf game to be more consistent?

The mental preparation for movement, which you will learn with the Alexander Technique, will allow you to be more in control and more yourself so that a good stroke will be down to you, rather than a hap-hazard stroke of luck when you happened to find favourable conditions and are unaware of what these were and therefore unable to repeat them when you wish to.

Does Alexader’s theory on balance help in the game of golf ?

Yes Alexander’s principles are very useful for golfers. Learning to get rid of unecessary tensions before and during movement will help the  golfer to find the natural balance he will need to be able to use successfully his technical knowledge. Alexander has devoted a small chapter on the use of the eyes by golfers in his book ‘The Use fo the Self’.
