What's your Weyt Age?
Your Weyt Age is the age whose median strength matches your bench press and squat, ranked against real population data. Enter one good bench set and see it in thirty seconds; add a squat for the exact number. Free, no signup, and your numbers never leave your browser.
Most strength standards compare you with other lifters. The Weyt Age headline compares you with everyone: the Cooper Institute's one-repetition-maximum norms for the general population, by sex and age bracket, as published in the ACSM Guidelines. A second ladder ranks the same lifts against lifters who track their training (Strength Level data), a much stronger, self-selected crowd. Any single set of one to ten reps works: the calculator estimates your one-rep max from it. Bodyweight defaults to the adult average for your sex until you change it.
How it is computed
Each set becomes an estimated one-rep max (Epley: weight × (1 + reps ÷ 30)). The bench press is scored directly against the Cooper bench table as a ratio of bodyweight. Because no credible general-population squat norms exist, the squat is first translated into the bench press that sits at the same Strength Level percentile for your sex and bodyweight, and that equivalent is scored against the same table, which keeps both lifts on one calibrated scale. Each lift gives the age whose median person of your sex lifts that much; your Weyt Age is the median of the two, rounded. With no squat entered, the squat is estimated at your bench press's Strength Level percentile and the result is labeled estimated. Below the youngest published bracket the age is extrapolated from your percentile within it, down to 18, so a strong lifter keeps a number that moves. This is the same math, on the same published norms, that the weyt.ai app runs on your logged sets, and a test pins the two to the same number for the same inputs. The full method, with a worked example, is on how the Weyt Age is computed.

Strength standards by age
Want the full ladder for your age? The strength standards pages show, for every five-year age from 20 to 70, what each weight on the bar means against both populations, for twenty lifts: bench press, squat, deadlift, overhead press and more.
