CPI · Capacity & Performance Indicator — your overall score on a 0–100 scale, measured against age & sex standards. 40 is the functional health standard for your age, so the average adult lands in Functional by design. The higher you go, the more strength, cardio, core & mobility capacity you're carrying.
The CPI is a performance indicator, not a medical or VO₂ measurement. Fitness Age is an
estimate based on age/sex performance norms. Not medical or professional fitness advice —
informational only. Consult a physician before starting any exercise program. Exercise
carries inherent risk of injury or death; by using this tool and any program you assume all
risk and release Rep Rally Live, Luke Guldan & The Guldan Ratio® from all liability to the
fullest extent permitted by law.
