Incorrect; like Coleman, his outrageous bis and a little lack of triceps separation on the medial and lateral heads fools some. In both cases they had big-time triceps size.
Forearms are cute but not at all essential in regards to great arms.
Incorrect as usual on your part. There is no comparison between Arnold and Coleman on arms; Coleman's arms were superior in all aspects. It's actually striking how similar Arnold's arms are to Gunther's.....great bis, and that's about it. Coleman had great tri size, outstanding separation from the front, and forearms that were not as far out of proportion with the upper arm as Arnold.
