Walt Stanchfield was a Disney animator who wrote handouts for the company on gesture drawing for more effective animation of characters. The handouts are loaded with drawing examples and will keep you occupied for weeks of learning. Just get out a sketchpad, open the PDF documents, and follow along with your pencil. This kind of thing is just great for getting one in the right frame of mind for drawing. We found this over at the excellent Drawn! blog.
