The Wilks scoring system has been recognized for enabling meaningful comparisons between weightlifters of different genders and across various weight classes. While the method demonstrated no gender bias in bench press performance, it did reveal a favorable bias toward intermediate-weight female lifters in the squat and a consistent unfavorable bias against heavier male and female lifters in the deadlift.

​

In 2020, the Wilks formula was updated with new coefficients tailored separately for male and female powerlifters.

​

These updated Wilks coefficients—applied by multiplying with the lifter's body weight—are derived from gender-specific data ranges: 40–150 kg for females and 40–200 kg for males.

​

Under both the original and updated systems, the Wilks Score is calculated by multiplying the Wilks coefficient by the total weight lifted (in kilograms).

The Wilks coefficient places greater emphasis on absolute strength rather than solely evaluating lifters based on relative strength in proportion to body weight.
