ok, everyone at the gym measures thier arms when they have finished pumping their arms. i personally measure my arms on the 2nd of each month after i wake up and flex them cold. i am going for accuracy to monitor my gains. right now i am at 17 5/8th. i have never measured pumped up. when people talk about arm size, are they meaning pumped, cold, non-flexed or what? just curious cause you here alot of measurements and i am curious how people are measuring.
