Grecian Ideal for Strength Training

Tl; dr version: Leonardo da Vinci rediscovered Vetruvius’s theory of proportions. Early strongmen then noticed parallels from Renaissance statues to how they trained their bodies.

The Golden Ratio.

I took most of my ideas from this site, though the idea is fairly widespread

How it practically looks:

1. Flexed arms 150% larger than the circumference of your non-dominant wrist.
2. Flexed calves should match flexed arms.
3. Your shoulders should be 1.618 times your waist.
4. Upper leg should be 75% larger than knee circumference.
