If you want to take your work further, studying 3D scans and simplified muscle block-outs remains the gold standard for modern artists.
The arm begins at the shoulder. In motion, the deltoid acts as the cap of a cylinder. When the arm raises, the deltoid shortens and bulges, but the critical detail for a sculptor is what happens underneath. As the arm abducts (moves away from the body), the armpit (axilla) opens up. The pectoralis major and latissimus dorsi stretch thin, revealing the underlying rib cage. A common mistake is sculpting the shoulder as a ball joint sticking out; in reality, it is a complex folding of skin and muscle over the thorax.

Look at the specific plate showing the arm twisting from palm up to palm down. When the arm raises, the deltoid shortens and
By visualizing the arm and hand as a series of volumes (spheres, cylinders, and boxes) that compress and stretch, the artist can sculpt poses that possess weight, tension, and gravity. You stop copying contours and start building structure. Whether you are working in ZBrush, clay, or pencil, understanding the mechanics of motion allows you to create figures that look like they are capable of moving, rather than just standing still.
