How to Draw Pecs and Abs Using One Simple Shape

#drawingtutorial #anatomydrawing #howtodraw When people try to draw pecs and abs, they usually start drawing muscles one by one… and that’s usually where things go wrong. Because chest anatomy isn’t just a random stack of muscles. The pecs, rib cage, and abs actually follow a simple underlying structure that sits under the rib cage and tapers down into the pelvis. Once you understand that structure, the muscles stop feeling confusing and start making sense. In this video I break down the simple torso framework I use to organize pecs and abs before drawing the detailed anatomy. Instead of memorizing ten different muscles, you can think of the torso as one structural shape that holds everything together. You’ll see how this structure works across multiple drawings, including a skeleton reference, simplified abs diagrams, and full muscle anatomy sketches. Once that framework clicks, placing pecs and abs becomes much easier no matter the pose.
