Here's my view on why Arnold's body is perceived to be the greatest of all time.
1. FACE. He had a very good looking, manly face. The hair was perfect for the era (1960's/70's) and structurally his face demanded attention. Great jawline and lips. Great eyebrows that give a very relaxed, yet sexy look.
2. CHEST. One of the best chests of all time, and the best chest of his era. It was huge, ripped and full in upper/mid/lower. He knew how to pose it and it stood out big time on stage.
3. SHOULDERS. Small enough not to overshadow his arms or chest, big enough to be seen.
4. ARMS. Some of the biggests arms in the game, especially at the time. His right arm had a fantastic peak, which he made sure that everyone knew was there. Triceps weren't too small and neither were forearms.
5. BACK. Ripped to shreds. Big enough to dominate anyone, small enough not to overshadow his front.
6. WAIST. Trimmed, tight and cut. Never bloated and always looking slim. He could hit a vacuum and the waist stayed small in every single pose he hit.
7. THIGHS. Not too small, not too big. Shredded and seperated. Accentuated his upperbody magnificently. Long muscles and great shape to them.
8. CALVES. Started off small, got them to be huge. A talking point to make sure people would talk about them for years to come. Still some of the best calves ever.
I know, gay as the day is long, but if you have any other reason why he was the greatest, let's hear them.
