Thank you all for you comments. Yes, this was an interesting class to work iwht as I am not used to this type of chair, so we were very creative with it's usage. I really liked the challenge of keeping the pedal split as it shows any imbalances instantly. Now I learned this is not the usual usage, so I suppose this class added to the pilates repertoire, by accident. we all loved the challenge.
thank you Niedra! Always enjoy your knowledge and your teaching. Thank you for talking us through the springs ~ still not sure its clear why there are outside and inside springs? :)
