I've had lessons with Rivca Cohen at different A.T. workshops. 

Three times in Denmark and once in Germany. 

Alexander Technique is not an easy thing to explain, so whatever you need to convey to a student, you are almost bound to use metaphors or phrases that consist of something that can be eye opening.

I carry two phrases with me that Rivca gave me at my lessons which I consider useful.

1/ Release into the activity. (As in.. not tensing into the activity)

2/ If it's choice its good and if its habit it is bad. (As in..If I feel like pulling myself down, let it be my choice and not my habitual behavior)

Hope these phrases can be useful for you to.
