USAPL Race Calculator Online

Show Your Love:

The United States Powerlifting Association (USAPL) Race Calculator is an indispensable tool for powerlifters and fitness enthusiasts alike. This calculator measures an individual’s relative strength in the sport, which is paramount in shaping training strategies and monitoring progress.


The USAPL Race Calculator utilizes the Wilks Coefficient, a formula developed to assess the strength of a powerlifter. This sophisticated calculator considers an individual’s gender and weight along with their lifting total (comprising of squat, bench press, and deadlift weights) to provide a standard strength score.

Detailed Explanation of the Calculator’s Working

The USAPL Race Calculator’s algorithm includes several steps. First, it records the lifter’s body weight, gender, and the combined weight of their primary powerlifting lifts. Following this, the formula calculates the Wilks Coefficient, resulting in a numerical representation of the lifter’s relative strength. This output aids in comparing performances across diverse weight categories and genders.

Formula and Variable Description

The calculation uses different formulas for males and females, each employing six coefficients to modify the body weight input:

Wilks Coefficient = Lifting Total * (500 / (a + b*Body Weight + c*Body Weight^2 + d*Body Weight^3 + e*Body Weight^4 + f*Body Weight^5))

Here, the variables ‘a’ through ‘f’ are constant coefficients, while the ‘Body Weight’ and ‘Lifting Total’ are inputs.


For instance, let’s consider a male lifter with a total lifting weight of 700kg and body weight of 90kg. Applying these values in the formula gives us a Wilks Coefficient of 45.71. This score is the measure of the lifter’s relative strength.


Training and Progress Tracking

One of the primary applications of the USAPL Race Calculator is to guide an individual’s training regimen and track progress over time. By assessing relative strength changes, one can gauge their improvement. H3: Competitions The calculator is also used in powerlifting competitions to fairly compare the performances of participants across different weight categories and genders.
