      Body Shape Rating (BSR)

      More information of Fit3D's Body Shape Rating wellness metric.

      What Is BSR?

      Body Shape Rating (BSR) is a wellness score that measures how your body shape relates to known cardiovascular and metabolic health risks. It answers the question:

      “Is my current body shape increasing or decreasing my likelihood of developing certain health issues?”

      BSR is based on a combination of 3D body measurements and health risk correlations—not just weight or body fat percentage. It’s a holistic indicator of your overall shape wellness.

      How It’s Calculated

      Fit3D analyzed data from over 26,000 3D body scans, evaluating correlations between shape-based indices and health outcomes. From that data, Fit3D developed a weighted composite score that blends multiple shape and proportion metrics, including:

      • SBSI (Surface-Based Shape Index)

      • ABSI (A Body Shape Index)

      • Trunk-to-Leg Volume Ratio

      • Body Fat Percentage

      • BMI

      Each variable contributes to how your body shape compares to the broader Fit3D population in terms of shape-related wellness.

      The Fit3D BSR algorithm is proprietary, but the general principle is:

      • A higher BSR means your body shape proportions (waist-to-hip, waist-to-chest, etc.) align more closely with patterns linked to lower health risk.

      • A lower BSR suggests that fat distribution or shape proportions may be more strongly associated with elevated health risk.

      What’s New

      The BSR scale now ranges from 0 to 100, where:

      • 50 = average for the Fit3D population

      • Higher than 50 = lower shape-related health risk

      • Lower than 50 = higher shape-related health risk

      The updated formula provides a clearer bell curve, showing more realistic clustering of scores near the population average.
      If your BSR appears significantly different than before, it’s due to a recalibration—not a sudden change in your health.

      Interpreting Your BSR

      Score Range Category Meaning
      80–100 Excellent Ideal body shape profile associated with low health risk
      60–79 Healthy Balanced proportions; moderate risk reduction
      40–59 Needs Improvement Above-average shape-related risk
      Below 40 High Risk Body shape patterns linked to higher cardiovascular risk


      Remember: BSR is not a judgment—it’s a data-driven reflection of how your shape compares to others with known health outcomes.


      How to Improve Your BSR

      The most effective ways to increase your BSR are to:

      1. Reduce waist circumference.

      2. Increase leg and trunk muscle mass.

      3. Lower overall body fat percentage.

      This generally comes from a mix of good nutrition, resistance training, and regular activity.
      Consult with your trainer, nutritionist, or healthcare provider to design a plan that fits your goals.



      How Owners & Coaches Can Use BSR to Drive Retention and Revenue

      🔹 At the First Scan (Day 0)

      Use the BSR to establish a baseline and create an emotional “aha moment”:

      • Show clients where they currently fall on the 0–100 scale, and explain that it’s not about weight—it’s about shape and health risk.

      • Position the BSR as a starting score to improve, just like a fitness game.

      • Use language like:

        “Most people start between 45–65. The goal over the next month is to move this number upward. That means your shape is becoming healthier—even before major weight loss happens.”

      This helps clients see the value in the scan immediately and creates anticipation for the follow-up session.

      🔹 At the Second Scan (4-6 weeks)

      Use BSR as a proof-of-progress and retention tool:

      • Celebrate even small improvements (+3–8 points is typical early on).

      • Visually show before-and-after body shape changes alongside the improved score.

      • Reinforce the value of their membership or coaching plan by connecting results to effort:

        “You’ve improved your BSR by 6 points in just one month—that’s a measurable improvement in your shape wellness. Let’s see how much more we can do in the next 30 days.”

      This approach boosts retention, upsell conversions, and long-term client engagement, because clients see quantifiable evidence that your program works beyond the scale.
