1. What is the Wilks Formula?

The Wilks formula (or Wilks coefficient) is used to compare the strength of powerlifters 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:

• \( total\_kg \) — Total weight lifted in kilograms (squat + bench press + deadlift)
• \( coeff \) — Wilks coefficient based on body weight and gender

Explanation: The coefficient is calculated differently for men and women using polynomial equations that account for the non-linear relationship between body weight and strength potential.

3. Importance of Wilks Score

Details: The Wilks score is the standard method for comparing powerlifters across weight classes. It's used in competitions to determine the "best lifter" award and to rank lifters overall.

4. Using the Calculator

Tips: Enter your total competition lifts in kg, select your gender, and enter your body weight in kg. The calculator will compute your Wilks coefficient and score.

5. Frequently Asked Questions (FAQ)

Q1: What's a good Wilks score?
A: 300+ is decent for beginners, 400+ is very good, and 500+ is elite level. World-class lifters often exceed 600.

Q2: Why are there different coefficients for men and women?
A: The formulas account for physiological differences in strength potential between genders at different body weights.

Q3: Is Wilks used in all powerlifting federations?
A: Most federations use Wilks or a similar coefficient (like IPF's newer "IPF Points"). Wilks remains the most widely recognized.

Q4: How often is the Wilks formula updated?
A: The original formula from 1995 is still widely used, though some federations have adopted updated coefficients.

Q5: Can I use Wilks for other strength sports?
A: While designed for powerlifting, it's sometimes used informally for other strength sports, though other formulas may be more appropriate.
