The Biometric Body Index (BBI) is a revolutionary formula that goes far beyond outdated BMI charts. Instead of just height and weight, BBI combines four real measures of your body into one clear, motivating score from 0 to 100 showing you exactly how close you are to your ideal body. YOUR BBI SCORE, BROKEN DOWN Your score is built from four equally weighted pillars (25 points each): Weight Body Fat Percentage Waist Circumference Fitness Level The closer your BBI Score is to 100, the closer you are to your ideal body and you'll see exactly which areas to focus on next. HOW IT WORKS Personal Details: Tell us your basics and your goals. Body Goals: Set your target weight, waist and body fat. Body Scans: Use your camera to capture your current weight, waist and body fat percentage with guided, step-by-step instructions. Fit Test: Complete a quick, guided exercise to measure your fitness level. BBI Score: Get your full Biometric Body Index result with a detailed breakdown.
