What strength percentiles mean

A strength percentile is an educational fitness metric that ranks your one-rep max on a lift against age-, sex-, and bodyweight-matched peers using population reference tables — not a medical test or clinical assessment.

A global percentile compares your absolute lift to everyone in the reference group. A bodyweight-adjusted percentile accounts for size so a lighter lifter can compare fairly on bench press percentile, squat percentile, and other compound lifts.

Carthalis calibrates benchmarks for everyday lifters — useful strength standards by bodyweight context without implying medical diagnosis. A lifting percentile is motivation and training context, not a clinical score.

Strength by exercise and body weight

Compare major compound lifts with bodyweight-adjusted context. An average bench press percentile or squat percentile helps answer how strong am I for my body weight without treating strength as a medical measure.
