1. What is the Wilks Formula?

The Wilks formula is used in powerlifting to compare the relative strength of lifters across different weight classes. It calculates a score that normalizes lift totals based on body weight.

2. How Does the Calculator Work?

The calculator uses the Wilks formula:

Where:

• \( lift \) — The weight lifted in kilograms
• \( coeff \) — The Wilks coefficient (dimensionless)

Explanation: The formula multiplies the weight lifted by a coefficient that accounts for the lifter's body weight and gender.

3. Importance of Wilks Score

Details: The Wilks score allows fair comparison between lifters of different sizes by normalizing performance relative to body weight.

4. Using the Calculator

Tips: Enter the weight lifted in kg and the appropriate Wilks coefficient. The coefficient can be found in Wilks coefficient tables based on body weight and gender.

5. Frequently Asked Questions (FAQ)

Q1: 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.

Q2: How is the coefficient determined?
A: The coefficient is calculated using complex polynomial equations based on body weight and gender.

Q3: Is Wilks used in all powerlifting federations?
A: Most federations use Wilks or similar formulas (like IPF points) to compare lifters across weight classes.

Q4: Are there different versions of Wilks?
A: Yes, there have been updates to the formula over time. The current version is often called "Wilks 2020."

Q5: Can I use this for other strength sports?
A: While designed for powerlifting, it can be adapted for other strength sports with appropriate coefficients.
