Nori,
I have super duper upper arms, too.
At my highest (around 213 pounds), they were 17 1/2 inches in diameter. They were, by far, my biggest hang up about my body. I hadn't been sleeveless in public since about the age of 6.
There's good news, though! At 168 pounds, they've shrunk considerably. They measure about 13 3/4 inches now. Still considerably bigger than average, but I went to a formal Christmas party wearing a sleeveless (and backless!
) halter dress this year, and it was a big victory. Hang in there, girl!
As for me, I measure whenever I think about it, usually once a month or so - or if I'm feeling particularly skinny
cheers!
