April 01, 2023 | Lifestyle and Wellness

The US Navy body fat formula, developed by the US Department of Defense, has become a popular method for estimating body fat percentage among both fitness enthusiasts and professionals. This widely-accepted formula takes into account specific measurements, such as height, and neck and abdominal girth for males, while incorporating height, neck, waist, and hip girth for females. By utilizing these measurements, the US Navy body fat formula provides a reliable and accessible means to calculate body fat levels, helping individuals track their progress and make informed decisions about their fitness and health goals.
