earning to draw muscles may conjure medical charts in daunting details, but such complexity is unnecessary. We only need to know what shows up through the skin, since that's what we draw: in real life, you'd have to look hard to find someone whose body displays intense muscle detail (basically bodybuilders and some athletes). Similarly, it is only a niche of illustrators who give a lot of attention to muscle details in their work, such as artists for superhero comics.
This comprehensive tutorial explains the process of adding muscle detail to your drawings. It contains tips about drawing arm muscles, the torso, leg, and even explains how to give a character the appearance of body fat. Whether you're a cartoon artist or someone who wants to improve their anatomy drawings, this tutorial will be useful to you.
