How strong are you, really?
Enter one set. We estimate your one-rep max and rank it against real JustGains lifters, published strength standards, or an AI estimate when a lift is too rare for either, then a coach tells you what to train next. Every result says which it used.

How the ranking works
One lifter, one vote
Where enough people have logged a lift you are ranked against them, matched on sex and, where the data allows, bodyweight and age. Each lifter contributes their single best, so somebody who benches twice a week never counts more than somebody who benched once.
Standards as the backstop
Rarely logged lifts fall back to published strength standards, corrected for bodyweight and smoothed across age instead of jumping between brackets.
AI fills the long tail
For exercises too rarely logged for either, the levels are AI-estimated against the lifts we do publish standards for, then scaled to match whatever real lifters have logged it. You still get an answer, and the card tells you it was estimated.
Every result says which of the three it used, how many lifters were behind it, and how many sets those lifters logged. A rank you cannot source is worth nothing.
What the levels mean
Untrained
Where almost everyone starts. Nothing to be embarrassed about.
Novice
A few months of honest training. The fastest gains of your life.
Intermediate
A year or two in. Stronger than most people in any gym.
Advanced
Years of focused work. You stand out, and people notice.
Elite
Competitive territory. Very few lifters ever get here.
More than a one-rep max calculator
Most strength standards sites give you a table and leave. This one is built on lifts people actually logged, and it tells you what to do with the answer.
Ranked against real JustGains lifters wherever the data supports it, not only a published table.
Every exercise in the library is searchable, not just the big three.
Bodyweight and age are corrected properly, so light and older lifters are not quietly punished.
Add several lifts and see which one is holding the rest back.
A coaching read on your numbers: what is strong, what is limiting you, and three things to train.
