Wilks Calculator
What is Wilks Calculator ?
The Wilks Calculator is a tool designed to level the playing field between powerlifters of different body weights and genders. By using the Wilks Coefficient, the calculator assigns a score to each lift, allowing athletes and enthusiasts alike to easily compare performance across varying weight classes.
How the Wilks Calculator Works
The Wilks formula helps compare the strength of powerlifters. It considers the total weight lifted (squat, bench press, and deadlift) and the body weight of the lifter. The formula is:
Wilks Score = Total Weight Lifted x Coefficient
Where the coefficient is derived from a specific formula that considers gender and body weight. This coefficient changes based on the weight and gender of the individual.
Wilks Coefficient Formula
The coefficient is calculated differently for men and women:
For Men:
Coefficient = 500 / (a + b*BW + c*BW^2 + d*BW^3 + e*BW^4 + f*BW^5)
For Women:
Coefficient = 500 / (a + b*BW + c*BW^2 + d*BW^3 + e*BW^4 + f*BW^5)
Where BW is body weight, and a, b, c, d, e, f are constants specific to each gender.
Example:
Consider a male lifter who weighs 80kg and has a combined lift total of 600kg:
Using the male constants and plugging them into the formula, we can find the coefficient and then calculate the Wilks Score.
