his contest ready non-pumped arm was probably a tad under 19 inches

I’ve personally measured the arms of the hulking individuals listed below. All of them had placed in the top eight of a recent show, and the measurements were taken about ten days after the show, presumably when they were at their biggest from all of the post-competition carbs ingested.
BODYBUILDER A
Height: 6’0"
Weight: 286 pounds
Cold arm measurement: 20.62"
BODYBUILDER B
Height: 5’3"
Weight: 228 pounds
Cold arm measurement: 20.25"
BODYBUILDER C
Height: 5’7"
Weight: 214 pounds
Cold arm measurement: 19.62"
BODYBUILDER D
Height: 5’11"
Weight: 258 pounds
Cold arm measurement: 18.9"
If I published pictures of these bodybuilders, you’d see that Bodybuilders A and D were famous for their leg development, while Bodybuilders B and C sported larger arms in relation to their lower bodies, which were still quite well-developed by any standard.
bb B is lee priest and his arm was 20.25 inches 10 days post contest
bb A might be dillet and bb D is milos sarcev i'd say
