BMI (body mass index) = weight(kg) ÷ height(m)^2. It’s a quick, population-level screening metric for weight status.

What are BMI limitations?

BMI doesn’t separate fat from muscle and ignores fat distribution. Athletes, older adults, pregnancy, and children need better context or different tools.

What should I track alongside BMI?

Consider waist/WHR, body-fat estimate, weight trend, and training performance—not BMI alone.
