I will keep this review short and on point. I do not think Pilates and yoga should be combined in any way, shape or form. They are two separate forms of exercise and have their own rules, principles and outcomes.
Pilates is a safe method of exercising that doesn't make the body bend in any unnatural way or go into any movement that we do not already use in our daily lives. Yoga is almost the opposite. The movements in yoga are those of extremes and in my opinion only experienced and knowledgeable people should do it. Those people are familiar with moving their body to the extremes through safe methods whilst the casual practitioner can do a lifetime of lasting damage to the body. One sudden movement in a complicated position can dislodge something, twist something, strain something, break something etc.
I am all for exercising and living healthy but I also think that people do not educate themselves enough and do not go into exercising with a concentrated and prepared mind so the exercises given to them should be the safest and harmless as possible. Then the person can get all the benefits it they go into it with their heart and mind but also if they do not, they will not suffer any consequences. That is why I believe that combining Pilates and yoga is not a good thing or a good way to go.
Apart from that, the book is not meant for beginners or for people who have never heard of any basics of Pilates and/or yoga. This book offers some good advice in certain areas and some exercises and it offers a nice sequence of exercises but that is pretty much it.
