How do you measure your arm?

[amusclehead]

Sometime i've always wondered. Okay, so you take a bicep pose. Does it matter, for measurements, if the lower part of your upper arm is parallel with teh ground, or if it slopes downwards? I find that with my naturally small muscle bellies, if I start off with the arm parallel to the ground, the lower it(so the lowe rpart of the upper arm is at a slight downward slope), my muscle bellies tighten and my arm is like 1/2'' larger. Just wondering if this is okay to measure this way, or the upper arm must be parallel with the floor

How can you have small anything when you spend 1300 dollars a month on food and supplements?
