Per request in the title: The 4 along each side we call “6-Pack” (maybe should be 8 pack) are Rectus Abdominals: The Tight Tidy set running from The Pectorals down toward the Pelvis at the Inguinal Ligament are in order top to bottom: External Oblique, Internal Oblique, and Traversus Abdominus. The line running down the centre between the 6Pack is the Linea Alba and the line running between 6Pack and Obliques is Traversus Abdominus! Who knew while searching Porn I’d have the opportunity to “Geek Out,” on my recollection of Grey’s Anatomy at the same time? I thank you for the question! FUCK SHE’S HOT!
