Does anyone know of any useful and informative Art Books that help one with drawing the Male Anatomy?

One of the best books out there is entitled "Dynamic Anatomy" by Burne Hogarth. Also "Dynamic Figure Drawing" and "Dynamic Heads" by Burne Hogarth. Your local library or bookstore should have copies of these, as they've been in print for quite some time and are very popular among artists, especially those learning to draw male figures for "superhero" comics. All three of these books accent all of the muscle groups from head to toe in the male figure, making it easier to memorize where they are and how to make those muscles pop in your figure drawings.
