Sculpting absolutely taught me about anatomy. The best series of classes I had in art school were with figure sculptor Louis Marinaro at U-M's art school, and this included a month-long workshop focussing on anatomy. The workshop was designed to improve your figure-drawing, because, frankly, nothing teaches you about plane-change like actually working in 3 dimensions.
The classic Houdon ecorche is a very valuable study tool. The parts of the figure are varied enough to allow you to generate a number of poses from the presented pose with a little bit of thinking and, yes, the help of charts and illo's like in the Richer and Albinus books.
I once owned a 12'' Houdon. it was from Sculpture House, and at that scale I was not pleased with the detailing. The forms of the arms and back were not well-defined, and there was no sense of the interlacing of the serratus muscles. I bought the next size up Sculpture House offered, 14 or 16'', I forget which, and the figure details were much better. The last time I moved, when I got married, I just gave my Houdon to the sculptor I'd been rooming with, rather than have to move one more thing. Since then I've thought about getting another, but definitely no smaller than 14-16". But the idea of just making one is compelling...
