How to measure

Measure your shoulders around their widest point, arms relaxed at your sides.
Measure your waist at the navel, relaxed, not sucked in.
Use the same unit for both — the ratio is the same in cm or inches.
The 1.6 figure is a popular reference (the 'Adonis index'), not a medical standard.

Questions

The often-quoted reference is about 1.6. Anything moving toward it reads more athletic, but there's no single correct number.

Build your side delts and upper back, and reduce waist fat. Both change the ratio.

For many men it takes years of training and low body fat. Progress toward it is visible long before you reach it.
