- Pectoral muscles are thick and full, with clear separation of the pectoralis major, and a noticeable chest groove
- Shoulders (deltoids) are very round and broad, with the anterior, middle, and posterior delts all prominent
- Arms are robust, especially the biceps peak is very high, the triceps horseshoe shape is also obvious, and the overall arm circumference looks large
- Abs present a clear six-pack (even approaching eight-pack), with obvious rectus abdominis blocks, and the Adonis lines / external obliques are also deep
- Overall body fat percentage is low, with some veins visible under the skin (especially in the forearm and abdominal areas), belonging to a quite lean but high muscle mass body type
