How to Measure Correctly
For accurate results, measure your neck at its narrowest point and your waist at its widest (for men) or at the navel (for women). Women should also measure hips at their widest point. All measurements should be taken with a flexible tape measure.
Why Body Fat Percentage Matters
Unlike BMI, body fat percentage distinguishes between fat and muscle mass. Knowing your body fat percentage helps set realistic fitness goals and assess health risks more accurately than weight alone.
