1. What is the Wilks Score?

The Wilks Score (also called Wilks Coefficient or Wilks Formula) is a coefficient used to compare the strength of powerlifters while accounting for differences in body weight and gender. The UK version uses specific coefficients for British lifters.

2. How Does the Calculator Work?

The calculator uses the Wilks formula:

Where:

• \( total \) — Total weight lifted in kg (sum of squat, bench press, and deadlift)
• \( coeff_{UK} \) — UK-specific coefficient based on bodyweight and gender

Explanation: The coefficient is derived from a polynomial equation that normalizes scores across different body weights and genders.

3. Importance of Wilks Score

Details: The Wilks Score allows fair comparison of strength between lifters of different sizes and genders, making it valuable for competitions and tracking progress.

4. Using the Calculator

Tips: Enter your total competition lift in kg, select gender, and enter your bodyweight in kg. All values must be valid (total > 0, bodyweight > 0).

5. Frequently Asked Questions (FAQ)

Q1: Why use the UK version of Wilks?
A: The UK version uses coefficients specifically calibrated for British lifters, providing more accurate comparisons within UK powerlifting communities.

Q2: What's a good Wilks Score?
A: Scores vary by gender and experience level. Generally: 200-300 (novice), 300-400 (intermediate), 400+ (advanced), 500+ (elite).

Q3: How often is the Wilks formula updated?
A: The formula is periodically revised to reflect current population data. This calculator uses the most recent UK-specific coefficients.

Q4: Does Wilks work for extreme bodyweights?
A: The formula is less accurate for very light or very heavy lifters outside typical competition ranges.

Q5: Can I compare UK Wilks to international Wilks?
A: Scores will be similar but not identical. For international comparisons, use the standard Wilks formula.
