Thank you to everyone for the kind comments. In response to Linda Tonkin's question: One of the reasons Joe Pilates developed his work was in response to what the rigors of the industrial revolution and modern life to the human body. I use the term 'hygiene' to dovetail on this idea to bring to awareness that in modern life we need to take care of our bodies and in particular our spines in the same way that we practice oral hygiene. This practice need not take a long time, but for the best results it should happen daily and consistently. Personally I have found that I often neglect my spine because I feel I do not have enough time to do a full series on the mat or the equipment. The idea of practicing spinal hygiene allows me to take 5 or 10 minutes for self care and the benefits are infinitely more that doing nothing.
