What is DOTS?

DOTS is the official strength coefficient used by the International Powerlifting Federation (IPF). It provides a fair comparison between lifters of different bodyweights by adjusting your powerlifting total using a polynomial formula.

Why DOTS replaced Wilks

The original Wilks coefficient served the sport well for decades but had inconsistencies at extreme bodyweights. DOTS was developed using modern powerlifting data to provide more accurate and balanced coefficients across all weight classes and genders.

The formula

DOTS = Total × 500 / (a×BW&sup4; + b×BW³ + c×BW² + d×BW + e)

Where BW is bodyweight in kilograms and Total is the sum of your best squat, bench press, and deadlift.

Frequently Asked Questions

A "good" DOTS score depends on your experience level. Beginner lifters typically score under 150. Novice lifters range from 150–250 and have a solid foundation. Intermediate lifters (250–350) train consistently and have good technique. Advanced lifters (350–450) compete at high levels. Elite (450–550) and World Class (550+) represent the top tier of competitive powerlifting. For serious training, aiming for roughly 50 DOTS points of improvement per year is a solid benchmark.

DOTS is the newer, more accurate standard. The IPF officially adopted it to replace the original Wilks coefficient. DOTS incorporates modern powerlifting data and provides more balanced coefficients across all bodyweights and genders. Wilks served the sport well for decades but had inconsistencies at extreme bodyweights. For official competition, DOTS is always used.

DOTS uses a polynomial formula: DOTS = Total × 500 / (a×BW⁴ + b×BW³ + c×BW² + d×BW + e). The coefficients (a, b, c, d, e) differ for males and females to account for differences in strength distribution across bodyweights. Your total is your best squat + bench press + deadlift, all in kilograms.

Heavier lifters have biomechanical advantages including more muscle mass and leverage. A 100 kg lifter and a 60 kg lifter totaling the same weight represent very different relative strength levels. DOTS levels the playing field by scaling your total against your bodyweight, enabling fair comparison across weight classes and mixed-gender competition.
