I can guarantee you that ronnies arms aren't close to 24 inches.
In a vid I saw some time ago (posted here om musclemecca as well), when ronnie was in China I believe, his arms was about 22 iches in that video, and it was just after Mr. Olympia 2004..
Yep i remember that..and Ronnie was at his biggest in 04.
Hands down for Phil Heath and Evan Centopani(hence my name). I like both of there arms because they have lots of meat in the bi's, but not toooo much of a peak, just a nice curved little peak to them. Too much of a peak makes them look small and pointy
