Looks like it will be helpful
Format: Audiobook
I'm not very far into this one yet, but so far, I love it. I bought the kindle and audible versions. It is nice to be able to listen to the exercises to go through them, and to be able to look up the specifics of any exercise. With whisper sync, I can point to an exercise in the kindle, and have audible read it to me. Great.
the exercises I have tried so far seem like they are going to be helpful.

Great Resource Even for Non-Professionals
Format: Paperback
I am not a psychotherapist, but I ordered the workbook to learn more about somatics. It’s a very good resource from what I’ve experienced so far. I love how the concepts are plainly explained in (mostly) everyday language. I’m a helper and healer by nature, and I think I will get a lot of mileage out of the well-presented activities in the book. If you’re not a professional but are looking for ways to expand your knowledge of healing, trauma response, and the human body, you’ll like the practical nature of this one.

What a FANTASTIC resource (WITH PDF FILES!!!)
Format: Paperback
I normally do not write reviews on Amazon, but thought I would do so in this case. I bought the book a few months ago and have really begun to digest the amazing quality of work that has been put into this. Prior to purchase I almost did not buy since someone else noted in their review that there are no PDFs. I reached out to the author, and she was very responsive and warm to my concern and advised there is a link within the book to download the PDFs. Sure enough, the book arrived and I was able to download the digital files! I have used to book and its tools to create two therapy groups that are heavily influenced by the content. After running both groups three times, I nothing but good things to say about this resource. My clients, who initially were resistant to somatic work, have all come around to love this group. In fact, they are two of the more popular groups at my program! Individuals who have been so traumatized that their usual report of "I feel nothing" has shifted. One client has been able to turn her whole narrative of her body being the enemy (for betraying her per trauma) to "my body empowers me. Even when I don't like what it is telling me, it is protecting me and moving me through life." I am so grateful for this book and the different perspective that it provided me in my practice.

AMAZED
Format: Paperback
This book is an incredible tool to add to the way I practice. I intuitively already used a lot of skills in this book and never realized what I was doing. I've always had this innate understanding that the body plays such an important role in healing. No wonder people gain a ton of weight after sexual trauma, or why we feel so good after exercise, yoga, dance etc. I was trained in a somatic and attachment focused protocol for EMDR and have been so intrigued to learn more about somatic exercises to incorporate with my clients. I'm so excited to start using this material! This has been on my wishlist for a long time, go ahead and buy it! You won't regret it.
