Per-lift — Barbell Lifters
What these circles mean
Each ring compares you to a different group. As the group gets more specialised, the comparison gets tougher — beating 70% of barbell lifters is a much harder feat than beating 70% of the general population.
How accurate is this?
These percentiles are estimates anchored to the Kilgore strength standards and calibrated against published population distributions. They are informed comparisons, not exact rankings. Age adjustments are handled automatically by the underlying standards data.
Frequently asked questions
What does 'stronger than X%' mean?
It means your 1-rep max is higher than that percentage of people in the selected group, adjusted for your bodyweight and age.
Which group should I care about?
Most people find the Barbell Lifters ring most meaningful — it compares you to people who specifically train with a barbell, the fairest peer group for strength athletes.
How do you estimate percentiles?
We use the Kilgore strength standards as anchor points (physicallyActive → elite, calibrated by age, sex, and bodyweight) and interpolate where your lift sits within each group's distribution.
Should I enter my true 1RM or an estimate?
Enter your best 1-rep max. If you only know a recent heavy set, use the One Rep Max Calculator to estimate it first.
Does age matter?
Yes. The Kilgore standards account for age, so a 55-year-old and a 25-year-old at the same relative strength level will get similar percentiles.
