BMI
BMI is a population screening tool that got promoted to a personal verdict it was never designed to give. Here's your number — and its limits.

—“normal” weight range for your height
What BMI misses
It cannot tell muscle from fat, ignores where fat sits on your body, and shifts in meaning with age and ethnicity. A muscular athlete and someone carrying visceral fat can land on the same number with very different health pictures.
Use it as one weak signal among several — waist measurement, blood work, energy, sleep and how your training is going are all better guides. Besly tracks the trend of your weight rather than a single verdict, which is the more useful view.
