This book has very poor writing, with many spots of weird editing and layout. I don't know if English is the author's first language or not, or it was due to being lost in translation.
This is not all Pilates, there are some Yoga poses mixed in the sequence of exercises. The front cover is a yoga pose, and a very poor example at that. There is some very poor alignment with the cover photo.
On one page the author talks about spinal and pelvis alignment and positioning. She describes the same thing twice but says they are two different positions and to find something inbetween. But it's the same position in each description!
Also, a lot of the classical exercises are given new and strange names: "Seated Balance" instead of Open Leg Rocker, etc. Some of the important exercises like the Hundred are left out completely. You can't have Pilates without the Hundred.
