this book I recently bought looks like it was made for body-builders or their trainers, but actually it`s great for artists too. I haven`t seen a book more packed with muscle anatomy illustrations like this one. Also, the quality is excellent. The illustrations are clean and feel 3d. The muscles and bones are often uncovered layer by layer showing exactly where is their origin and insertion or how their heads divide. And as we see all possible training poses, it`s great reference for riggers when checking the range of motion for a character and how the muscles or skin behave.
The third edition has 192 pages, and unlike others it also has female anatomy reference. At the very end is full muscle body in seen from side, front and back and skeleton front and back.
