Are 8 or 10 Pack Abs Impossible to Achieve?

When I was at the Grocery Store in Australia today I saw a guy on the cover of a Fitness magazine with 8 pack abs. I can get a 6 pack in 2 months thanks to my naturally slim body where I store no belly fat year round. I’m just wondering with a 16 inch torso at 5’4 do you think I can go beyond a 6 pack? It’s toned when I do get a 6 pack.

I saw a guy at the beach once who had a 10 pack and I couldn’t believe what I was seeing. I’m wondering with the easy ability to get a 6 pack can I work my way up to 8 or 10 pack abs?

My mom and dad also have incredibly toned torsos as well so I definitely am genetically predisposed to having a toned torso. My mom tells me that she can still get a 6 pack at age 60.
