- Navy Method: Uses neck and waist measurements (plus hip for women) for a more accurate estimate.
- BMI Method: Uses height and weight to estimate body fat (less accurate for muscular individuals).
- Circumference Method: Uses multiple body measurements for estimation.
Understanding Your Results
Body fat percentage categories vary by gender:
- Essential Fat: The minimum amount your body needs to function properly.
- Athletes: Typical range for athletic individuals.
