Just for the record...
I never claimed Kovacs had 18 inch arms or anything of the sort... I pointed out that they obviously weren't 25'' as the photo of him having them measured as such was suspect (there was only 9 inches of tape showing).
We had Greg Valentino on TV over here in Europe and the Guinness Book of World Records people measured his flexed growths at 24 inches... anyone who thinks Kovacs arms were ever bigger than Valentino's lumps of scar tissue is a fool. You'd have to be 400 lbs lean to have non-synthol arms that size.
I'm not hating on WisconsinBB, he's certainly big enough to have a legitimate 20 inch arm... it's just that you have to be careful about arm measurements: slack tapes and poor measuring technique can add to measurements in a way that few bodybuilders are willing to acknowledge.
Just for a little perspective:
-a 240 lb Arnold had 19.625'' arms (as measured by Arthur Jones)
-by his own admission here on GetBig, Shawn Ray had 18 and change inch arms (which puts my arms in perspective as I'm only 5'5'')
-a 225 lb off-season Lee Priest stretched the tape to 21.25'' (as measured by our own Tim Fogarty, which make my arms seem like breadsticks)
-an off-season Vince Taylor managed a 19.5'' arm (also measured by Tim Fogarty)
As I've explained before... because you are measuring circumferences, a 21'' arm is a full 36% bigger and stronger than an 18'' arm (all other things being equal) because it's a ratio of the squares of the measurements not a ratio of the measurements themselves.

PS... WisconsinBB, were you living in Fenamore (southern Wisconsin near Boscobel) last year? I trained with a guy down there who had a near 60'' chest at 310 lbs... might that have been you?
