Why Measure Body Fat?

Weight alone can be misleading. You might be gaining muscle and losing fat, but the scale stays the same. Tracking Body Fat Percentage separates your lean mass from fat mass, giving you a true metric of fitness progress.

How to Measure for Accuracy

  • Neck: Measure below the larynx (Adam's apple). Keep tape flat.
  • Waist: Measure at the navel (belly button) for men, or the narrowest part for women.
  • Hips (Women): Measure at the widest part of the buttocks.
