Five measurements, one accurate estimate.
Neck, chest, waist, upper arm, and calf (plus hip for women). More data points means a more accurate picture than the two-site Navy method alone.
We start with the U.S. Navy formula, then refine it using your chest, arm, and calf measurements to account for muscle mass distribution — reducing the error that comes from a waist-only approach.
From body fat percentage, we calculate fat mass, lean mass, your category, and BMI. Together these give you a complete picture of where you stand.
