Understanding Body Mass Index (BMI)
BMI is a simple screening tool that uses your height and weight to estimate body fat. While it's a quick starting point, it has significant limitations for active individuals.
Calculate Your BMI
BMI is a mathematical estimate and **not** a direct measurement of body fat. It cannot differentiate between lean muscle mass and adipose tissue (fat). For athletes, weightlifters, or those with high bone density, a "high" BMI may be a sign of peak physical condition rather than a health risk. Conversely, those with very low muscle mass and higher fat percentages may have a "normal" BMI but high health risks.
