I've bought this book 6 months ago, starting with the pelvis, legs, torso and arms, I still have yet more to learn with hand and the head ( I've always I always practised the head prior ).
This book isn't going to teach you a specific way to draw anatomy, as mentioned in the introduction. Its going to show you Bridgman's thought process.
The text is probably the most important part, rather than the illustrations, as they are more like supporting material. The best way I have learnt from him, is to read and draw the text as he has written. It helps develop his 'idea' into your drawings.
I have known about the anatomy for the human figure for years, but I have never thought of the way Bridgman has. It's almost an eye opener to how I see the human figure now. I almost see shapes when I look at people.
I've seen a guide on the book, and often mentions the inconsistencies within his work. And I think that's representative of his mindset. To not be so stuck on the small areas, but to encapture the idea with shape.
This is not a beginner book. It goes in-depth with the anatomy, which can be too distracting when you forget about basic form, gesture and rhythm.
If you want to benefit from his ideas, you have to actually study it ( draw ideas of the text, research the bones and muscles, make new abstractions and ideas) and not breeze through the pages.
