Um, everyone go get one of those flexible cloth (?) tape measures and see how big your arms are around. Maybe use a string, and then measure the string or something. Don't ask me why. I was just sitting here, NOT just getting back from the bar, dammit, because I didn't feel like leaving the house, and, well, I got bored. If U R bored, you can join in this charade.
Mine = 16.5" at bicep, 14" at forearm. I go to the gym tomorrow (missed last 2 days...aaaargh!), so I'm thinkin' maybe 17" when pumped. Is a 2.5" difference b/n upper and lower arm normal? Seems like not a very big difference. Maybe it's from all the typing.

We'll leave it at that.
.....hehe. I dressed up as Hans last Halloween. I took two long sleeve T's and stuffed pillow filling everywhere, and then sewed here and there to make 'pockets' for the filling to represent muscles. Then I put on long johns, and stuffed the filling in there to make quads and calves, and then put on my grey sweats and lifting gloves and a big belt. I here to tell you, I sweated my ass off. But then, this random drunk dude stole my buddies hat and came running towards me, so I tackled him and pinned him flat on his ass. I let him up, and he started towards me, but then thought twice and ran off. (I'm 6'5", and with that padded suit I was probably 3' across!) ...it was classic. Maybe this year, I'll actually find somebody to be Frans, so I can stop telling people, "Oh, Frans went to the bathroom. Sorry." ..you know the deal.
