What is the Wilks Formula?

There is one formula to calculate the wilks score for males & females.

Wilks score = W * 500 / (a+bx+cx2+dx3+ex4+fx5)

Where W is the weight lifted in kg

x is the weight of the lifter and letters from a to f are the coefficients. The coefficients for male & female are different.

Coefficients for men:

a = -216.04

b = 16.26

c = -0.00

d = -0.0011

e = 7.01 * 10^-6

f = -1.29 * 10^-8

Coefficients for women:

a = 594.31

b = -27.23

c = 0.8211

d = -0.009

e = 4.73 * 10^-5

f = -9.05 * 10^-8

Our wilks coefficients calculator considers these coefficients for male & female to calculate their wilks score.
