I know the Marabout guides for many years and I did not hesitate a second when I saw this one to control. However I was very disappointed by its content. I expected very simple instructions and everyone that is not the case. The drawings are not very intuitive and we must already know a little the principle of Pilates to understand certain positions which is a shame when you know the importance of these positions to fully pass a motion. The explanations are not always very clear. It can be a good reminder for those who have already done Pilates and who want a reminder of the essential, but not for beginners.
