These are used to determine the Strength Total and Strength Score.

• Deadlift 1RM (lbs)

• Squat 1RM (lbs)

• Bench 1RM (lbs)

These are used to calculate the Built Score and, subsequently, the Healthspan Age.

• Grip Strength (lbs)

• Push-ups (max reps)

• Single-Leg Balance (s)

• Sit-to-Stands (10s)

• VO₂ Estimate (ml/kg/min) is tracked but not currently used in the core derived scores.

The Built Score measures functional fitness and balance relative to the entire group. It uses a normalization process to compare an athlete's results in different units (e.g., pounds, reps, seconds) on a single scale.

1. Establishes the group average for comparison.

2. Converts each raw Functional Metric (Grip, Push-ups, etc.) into a standardized score relative to the group.

3. The average of all four Z-Scores is converted to a final 0–100 scale, where 50 is the average for the entire group, and each 10 points represents one standard deviation.

This is a simplified metric used for relative ranking, based directly on the raw Strength Total.

Strength Score=Round(Strength Total/10)

This is a simulated metric used to provide an age-related context to the athlete's functional health. Lower is better.

HealthspanAge=Max(20,80−Round(Built Score×0.6))
