would love to hear the rationale behind that argument
does he mean your arms get fatter with the weight gain?
Really good question. I think he means muscular bodyweight. He's essentially referencing genetics in that you can't "spot increase". The only way to make your arms bigger without oil is to make your whole body bigger.
Here's a quote from Poliquin about the subject and I found a 3rd party link to his work. There's a lot of stuff from the really old boards like 1999 to early 2000s that I hope someone preserves. Poliquin, the old MM2000. There was some great info
Charles PoliquinTypically, you have to gain 15 pounds of overall body weight to add an inch to your upper arm measurements. Now, if you want to go from 21 to 22-inch arms, which is enormous, it'll be more like a 25 pound gain. Weider writers claimed that Arnold used to have a 22 inch arm cold. Arthur Jones said they were full of shit. Arthur Jones was right: the Weider camp was full of shit. For Arnold to have a legitimate 22 inch arm, he would've had to weigh 308. If you're going from a 14 inch arm to 16, then 30 pounds will do it. But going from 18 to 20 inches will require more like a 50 pound gain.
