I recommend this book to people who want to understand Health Kinesiology in greater detail. It's very easy to read and explains about the history of Health Kinesiology, how it works, etc. You can take a look at the table of contents and some preview passages from the book at this link. I also have a copy of the paperback version in my office for clients to browse.
Jane Thurnell-Read is a UK-based health kinesiologist practitioner and teacher who practiced HK for over 20 years. She is now focused on writing and creating the test kits that I use in my practice.
If you don't have a Kindle device and/or no interest in Amazon Prime, the book is available for $14.60 (today's current price).
