Arnold bicep workout pics 22 INCHES!!

This how the legend trained his 22inch arms .Look at the thickness of the bicep (lower and upper part) with incredible peak no one can match. Arnold had well developed outside bicep and the inside bicep. I have searched a lot on the internet but there is not a single picture where he used machines to train his bicep (in the 60s nd 70s). Dumbells, barbells, ez bar ,preacher pad, arm blaster is all he trained with.
