What is this tool?

BMI can sometimes be inaccurate for very muscular individuals because it doesn't separate muscle from fat. The Body Adiposity Index (BAI) is a popular alternative that uses your hip size measurements instead of your weight to estimate your true body fat percentage.

How it works?

Input your height and your exact hip circumference measurements (in cm). The tool calculates your body fat ratio using validated anatomical formulas.

Is it free for all?

Yes, Free for everyone! An excellent, alternate body composition tool for athletes, bodybuilders, and fitness enthusiasts.
