Turn a working set or target into usable training loads.
Put a lift or total into a named comparison model.
Prepare bodyweight class and attempt selection.
Estimate energy needs, targets, and body metrics.
Inspect tables, methods, data, and caveats.
Estimate a 1RM from any set, see where a squat, bench, deadlift or total ranks among recorded competitors, and check what counts as a good lift for your bodyweight and age. Every number names its formula and its dataset. Nutrition targets — TDEE, calories, macros — use the same saved profile.

The powerlifting cohorts use 186,303 eligible source rows from the OpenPowerlifting CC0 dump dated 2026-05-16; 186,218 rows contribute 615,721 lift observations in the window from 2025-05-10 through the latest included meet on 2026-05-10. Cells are segmented by sex, per-year age (15–80), IPF bodyweight class and equipment. Cell n counts observations for that lift, not unique people. /rankings does not estimate a general-population percentile.
DOTS (Konertz, BVDK 2019) is the de facto raw-open scoring standard on OpenPowerlifting and US raw federations like USPA — not an IPF formula (the IPF's own official coefficient since 2020 is IPF GoodLift). It gained ground because the older Wilks formula systematically under-scored heavier lifters. The table takes the current total-kilogram percentile anchors for male 83 kg class, age 30, raw, then converts each total to DOTS at exactly 83.0 kg bodyweight. A 582.5 kg total is p50 for that total cohort and scores 393.2 DOTS at 83.0 kg; this does not mean 393.2 is the median of the cohort's row-wise DOTS scores.

Seven formulas are computed in parallel and their disagreement is surfaced as a low/high range plus half-range ±%: Epley, Brzycki, Mayhew (PMID 1614532), Lombardi, O'Conner, Wathan, and Lander. With the equations implemented here, the full range is about 5.6% at 5 reps, 6.2% at 8 reps, and 11.8% at 12 reps; it is an estimator-disagreement range, not a statistical confidence interval. The Prilepin volume table is the Charniga translation of A. S. Medvedyev, A System of Multi-Year Training in Weightlifting (Sportivny Press, 1986).
