Grip Strength Tracker Excel — Age/Sex-Normed Percentiles, an Established Mortality Predictor

Grip strength is one of the most-replicated simple biomarkers of overall muscular strength, independently associated with all-cause mortality and functional decline in large population studies -- alongside VO2 max, it's considered one of the strongest "low-tech" longevity signals available, and it only requires a $20-30 hand dynamometer to measure. This tracker logs both hands, places your result in an age- and sex-adjusted percentile band, and flags concerning asymmetry between your dominant and non-dominant hand.
