Body Measurements

What it does

Record circumference measurements — neck, chest, waist, hips, arms, forearms, thighs and calves — with notes, and track the change between entries. These measurements feed directly into FitScan's body-fat calculation, where the U.S. Navy circumference method is more accurate than a BMI-based estimate.

Why it matters

Your waist can shrink and your arms can grow while the scale sits still. Measurements catch the progress the scale hides — and make your body-fat number more accurate.
