A body fat percentage typical of people who exercise regularly and are in good physical condition.

Clinical Note: The US Navy method is a highly accessible estimate based on circumferences. For females, the hip measurement is required by the formula. For males, the hip measurement is ignored.

How this is calculated

Uses the US Navy circumference method: a logarithmic formula on your neck, waist (and hip, for women) measurements relative to height, then categorized on the ACE (American Council on Exercise) scale. A tape-measure estimate, not a DEXA scan.
