About Body Fat Percentage
Calculation Methods
- Navy Method: Most accurate circumference method, uses height, neck, waist (+ hip for women)
- Army Method: Similar to Navy with different coefficients
- BMI-Based: Estimates from BMI, less accurate but only needs height and weight
Why Body Fat Matters
Body fat percentage is a better fitness indicator than weight or BMI alone. It distinguishes between fat mass and lean mass (muscle, bone, organs).
