Calf implants weren't even around during Arnold's time and even in the 1990's when someone got implants you could see the scar. There was not scars on Arnold's calves. And look at Arnold's calves now. They've atrophied. But I'm sure someone will say that he had them cut out.
Arnold had decent calves early on. He never really trained them but concentrated on arms and chest as most did in those days, and as they do today. He said after meeting and training with Reg Park he learned to focus more on the delts and calves.
I remember Joe Meeko, and exceptionally good and decent guy and great bber, insisted that Arnold had chest implants as well. You can see Arnold as a teen had an outstanding chest.
The jealousy among bbers knows no end and ever gets to the best of the.
