What the score does
Raw total favours heavier lifters. Wilks and DOTS multiply your lifted weight by a coefficient based on your bodyweight, flattening that advantage so a 60 kg and a 100 kg lifter can be ranked on the same scale.

Enter your bodyweight, what you lifted and your sex. We return your DOTS score, the modern standard, alongside the classic Wilks, so you can compare strength fairly across bodyweights and against anyone in the gym.
How it works
Raw total favours heavier lifters. Wilks and DOTS multiply your lifted weight by a coefficient based on your bodyweight, flattening that advantage so a 60 kg and a 100 kg lifter can be ranked on the same scale.
Wilks came first and ran federations for decades. DOTS is the newer fit to a broader, more recent data set and now leads most rankings. We show both: DOTS as the headline, Wilks so older meet results still line up.
Each formula uses separate coefficients for men and women, calibrated on that population, so the score is comparable across sexes. Pick the one that matches how you compete, or the numbers drift.
Both formulas were designed for a squat, bench and deadlift total. You can score a single lift to track it over time, but the strength bands assume a full total, so a lone bench will read lower.
Common questions
Ironstead logs every working set and keeps your estimated maxes current, so watching your bodyweight-adjusted strength climb takes no spreadsheet. Free for athletes.
Scores are for comparison and motivation, not medical or coaching advice. Federation rankings use their own official calculators.
