1. What is the Wilks Formula?

The Wilks formula (or Wilks coefficient) is used to compare the strength of powerlifters and weightlifters while accounting for differences in body weight. It allows for fair comparison between athletes of different sizes.

2. How Does the Calculator Work?

The calculator uses the Wilks formula:

Where:

• \( total \) — Total weight lifted (kg)
• \( coeff \) — Wilks coefficient (dimensionless)

Explanation: The coefficient is calculated differently for men and women based on body weight, using polynomial equations that normalize scores across weight classes.

3. Importance of Wilks Score

Details: The Wilks score is crucial for comparing strength across different weight classes in powerlifting and weightlifting competitions. It helps determine the most impressive lifts relative to body size.

4. Using the Calculator

Tips: Enter your total competition lift (sum of best squat, bench press, and deadlift in kg), your body weight in kg, and select your gender. All values must be valid (weight > 0).

5. Frequently Asked Questions (FAQ)

Q1: Why use Wilks instead of raw totals?
A: Wilks allows fair comparison between lifters of different body weights by normalizing scores based on body weight.

Q2: What is a good Wilks score?
A: A score of 300+ is considered good, 400+ is excellent, and 500+ is world-class for drug-tested lifters.

Q3: Does Wilks work for all weight classes?
A: Yes, it's designed to work across all weight classes, though it may slightly favor middle weight classes.

Q4: Are there different versions of Wilks?
A: Yes, there are older and newer versions. This calculator uses the widely accepted original formula.

Q5: Can Wilks be used for single lifts?
A: While designed for totals, it can be applied to single lifts for comparison purposes.
