Hi all. Like most, I struggled a lot with understanding the twisting and the arm attachment of the pecs. Looking for more info on it, I found a biomedical research paper from 2019 that was studying variations in the muscle. It has photos of pecs from real, cleaned cadavers, and a lot of photos of the attachment itself from different views. I will post a link to it here. If this causes an issue, I understand if we have to remove it : https://pubmed.ncbi.nlm.nih.gov/31061824/ And yes, according to that research paper, it's a little different from what Stan teaches us in the video. From my understanding : (without looking at the photos, this will make no sense) 1. The attachment has 3 layers of roughly the same length overlapping each other. - The clavicular section occupies an entire layer on its own and is separate from the rest. - The rest occupy the other 2 layers, connected by a U-turn at the most distal part of the attachment. 2. There's no difference between the sternal and abdominal sections at the attachment. The "U" turn is formed roughly at 2/3rds of the sternal section, and this is where all the muscle fibers twist. 3. Because of that U turn design and the fact that the clavicular portion is on a layer of its own : - The top of the sternal portion is at the most medial point of the attachment, and the fibers attach in a more and more distal point, until the 2/3rds split. - That "2/3rds" part of the sternal portion is at the bottom of the attachment, starting to form the turn. - From that point, the rest of the fibers go in the opposite direction, from distal to medial, blending the sternal and abdominal portion as if they were the same thing. - The "last fibers" of the abdominal portion thus attach at the most medial spot too, just next to the "first fibers" of the sternal section. 4. On the photo of the 5th assignment exercise, we can see a huge dimple. I think it is not caused by what Stan explains but by tendons. One of the photos showed a muscle that had a tendonous area right at that spot. Which also explains why it only occurs on some people. Anyways, because I had conflicting information, I was confused as to whether I should follow Stan's instructions, or the information I found on the research paper. I ended up doing a mix of both, and so I got a pretty weird result. I'm not pleased with it, but I was worried I'd be thought of as "wrong" if I weren't following Stan's instructions.

2022/10/12. Good morning everybody. Here's my latest long drawing (Conte B on HULU super smooth paper). If u have any advice or suggestion to improve it please leave a comment. Thanks and have a good day.

2022/10/12 . my priactice. need critiques..could some one give me some suggestions of structure exercise?
