Stone and Judith A. Stone, Wm. C. Brown, and An Illustrated Atlas of the Skeletal Muscles by Bradley S. Bowden and Joan M. Bowden, Morton Publishing Company (Both contain sketches of each skeletal muscle alone on the skeleton for easy visualization of the origins and insertions)--- might be helpful.
