Here is a book that is published by the guys who own the technology for the isometric exercises we are doing. https://www.amazon.com/Osteogenic-Lo...4416247&sr=8-1.

The book is not that well written i.e. needs editing but it has some interesting muscle and bone anatomy discussion. It may help you planning your strength training and it is cheap.
