Very cute.

core = everything above knees, above elbows and below neck.

core only excludes calves, forearms and your head.

go read a book motherfucker

not OP but core is loosely your abs and lower back.

However to keep progressively overloading your core you would need to engage a lot of the rest of your body. you most definitely would have "lacking" arms,legs, chest and overall back.
