Strength standards by age and weight take the single-lift bands, bench, squat, deadlift, press and the bodyweight movements, and read them all against the same person's age, sex and bodyweight. A strength score or strength comparison rolls those together, so instead of five separate labels you get one picture of where your whole training sits.
Why age and weight anchor everything
Every strength standard is read against bodyweight, because a lift scales with the muscle a frame carries, and against age, because strength rises into the late twenties and declines slowly after. Reading your lifts against your own age and weight is the only fair comparison, and it is why a single all-ages, all-bodyweights number would be meaningless.
Rolling the lifts into one score
A strength score, or strength comparison, normalises each lift to its own standard and combines them, so a lifter who benches at the intermediate band and deadlifts at the advanced one gets a blended picture. It is the same idea as a powerlifting coefficient, and it stops one strong lift from hiding a weak one.
Using the standards well
The point of strength standards by age and weight is calibration, not judgement. They tell you which lifts lead and which lag, so training can address the lagging ones, and they set fair expectations for how fast the bands move. They do not tell you how to train, only where you currently stand.
Questions people ask about strength standards by age and weight
What are strength standards by age and weight?
They place each of your lifts in a band, from untrained to elite, read against your own age, sex and bodyweight, so the comparison is fair rather than against a lifter of a different size.
What is a strength score?
A strength score normalises each lift to its own standard and combines them into one figure, so a strong deadlift does not hide a weak press and you see where your whole training sits.
Why read lifts against age?
Because strength rises into the late twenties and declines gradually after, reading your lifts against your own age band is fairer than against a single all-ages figure.
