Hey, @Marty Bane! There’s a bulky book with gorgeous photos called “Anatomy for the artist”, by Sarah Simblet. It’s quite expensive, but, among the books I can remember, I guess it’s the one that best matches the constraints you listed. Alternatively, one thing I imagine you could do is to purchase one or more model photo sets here at Proko, then choose a bunch of images to print out and make a booklet for yourself. I’m suggesting this because Proko’s model references are among the best I’ve ever seen for drawing/painting, and I assume that doing this might turn out cheaper than buying a hard cover book. Plus, you’d get to choose the specific photos you’d print for your booklet, so it could be something super tailored to your needs. But, of course, feel free to do however you find best! Hope this helps!

Hi! For physical books, I would recommend checking out Eadweard Muybridge's collections. There's several out there but some of them are purely dedicated to the human figure in action.
