Actually the 8/10 pack your referring to is only one muscle; the rectus abdominus m. The 8 pack is a result of the tendinous sheath that surrounds the muscle itself. That being said, there are anatomical anomalies that could contribute to the "10 pack," heck some people are born with multiple spleens why not an extra tendon separation. the cadavers I studied were divided into 6 sections plus the lower part of the sheath, but they weren't fitness models...

Dude, this guy is Greg Plitt. He is NOT photoshopped, trust me.

Saying that the #1 fitness model in the world is photoshopped, now that's hilarious.

Greg Plitt brah...
