Log your five main lifts and see exactly where you sit on the clinical strength curve for your age and bodyweight, plus the next milestone to chase.
Your Numbers
Enter your heaviest single (a true or estimated 1-rep max). This is a one-time snapshot — it reads the research relevant to where you stand today, not your progress over time. Nothing is sent anywhere; the math runs entirely in your browser.
Enter the most strict pull-ups (or chin-ups) you can do in a single set with no added weight and no assistance. Leave blank if you can't do one yet. We convert your reps into an estimated one-rep max, so you get the same strength read-out as if you'd loaded a belt.
These benchmarks are population estimates drawn from published strength-standard tables and the epidemiology cited below — not a medical assessment or a diagnosis. Use them as a compass, not a verdict, and clear any new heavy training with your physician.
