Hi cats, it is a very different set of exercises, it relies on very small movements, but a lot of them, it is definitely something that you start at what you can do and work up to the count, somethings are much more difficult than others, but only because of the number of repetitions not the exercise itself.

May I suggest beginner callanetics, here is a small exert, the older woman is her mother who is in her seventies and was not able to do some of the exercises at first but as you can see is extremely flexible (much more than Me) now, also the younger woman that does some of the exercise demonstration in this exert is an instructor and therefore does the moves to perfection.
The beginner video is an excellent start to get to know the adaptations based on your bodies ability.

Callan Pickney suffers from Scoliosis, so I knew that her exercises would not be hard on the back, she is constantly reminding you through her video's how to not hurt your back but stretch it.

Hope this answers some of your questions.
