1. What is the Wilks Formula?

The Wilks formula (or Wilks coefficient) is used in powerlifting to compare the relative strength of lifters across different weight classes. It provides a score that normalizes lifted weights based on the lifter's body weight.

2. How Does the Calculator Work?

The calculator uses the Wilks formula:

Where:

• \( total\_lbs \) — Total weight lifted in pounds
• \( coeff\_kg \) — Wilks coefficient (dimensionless)
• 2.20462 — Conversion factor from pounds to kilograms

Explanation: The formula converts pounds to kilograms then applies the Wilks coefficient to calculate a normalized score.

3. Importance of Wilks Score

Details: The Wilks score allows fair comparison between lifters of different body weights, helping to determine the most impressive lifts relative to body size.

4. Using the Calculator

Tips: Enter total weight lifted in pounds and the appropriate Wilks coefficient. The coefficient varies based on gender and body weight.

5. Frequently Asked Questions (FAQ)

Q1: Where do I find my Wilks coefficient?
A: Wilks coefficients are published in tables based on body weight and gender. Many powerlifting organizations provide these tables.

Q2: Is Wilks score used in competitions?
A: Yes, many powerlifting federations use Wilks scores to compare lifters across weight classes in raw competitions.

Q3: What's a good Wilks score?
A: Scores above 400 are considered excellent for men, while scores above 300 are excellent for women. World-class lifters often exceed 500.

Q4: Are there alternatives to Wilks?
A: Yes, other formulas like IPF Points (formerly GL), Schwartz/Malone, and DOTS are also used in different federations.

Q5: Why convert to kilograms?
A: The original Wilks formula was developed using metric measurements, so conversion is necessary when working with pounds.
