yeah i have a thing with wanting a six pack too. im envyous of keira's stomach. i have a 2 pack right now and almost a four pack after i do 7 minute abs. by the way, i also think its sexy if you have those lower stomach muscles kinda like usher but not so big, kinda like maria sharapova's on si's swimsuit 2006. i was jealous when i saw that.
by the way, i only have a two pack because i run cross country and we do push ups and sit ups, ALL THE TIME.
