The U.S. Navy Body Fat Calculator offers a convenient way to estimate your body fat percentage without expensive equipment. By using simple measurements of your height, neck, waist, and (for women) hips, you can get a reliable indicator of your body composition. This method is widely used due to its simplicity and accuracy for the general population. Understanding your body fat percentage is more insightful than just tracking weight, as it helps differentiate between fat and muscle mass. Use this calculator to monitor your fitness progress, set realistic body composition goals, and maintain a healthy lifestyle.
