First of two overall reference page for arms. There’s no need to actually draw muscles on every character, but it truly helps to understand the underlying structure, especially when pushing the pose a bit more. One thing that’s often overlooked is the connection between the arm and forearm, as well as how the deltoid muscles (shoulder) interacts with the pectoral muscles (chest) when lifting the arms up (front view). Anyway, use this page as you please.
