Posing naked is definitely hard work. Try holding your phone in your hand with your arm extended in front of your chest; stay like that for five minutes. Andrea Garcia does the same kind of isometric exercises when she holds her arm above her head to give her tits extra perk! We feel for the girl, she needs a vacation.
We're not opposed to the idea of doing a whole shoot with Andrea lying down. There's a lot of neat stuff you can do when you're horizontal, and what's good for the spine of a gorgeous woman is good for humanity.
