1. What is the Wilks Coefficient?

The Wilks Coefficient (or Wilks Formula) is used in powerlifting to compare the relative strength of lifters across different body weights. It provides a score that accounts for body weight differences, allowing fair comparison between athletes.

2. How Does the Calculator Work?

The calculator uses the Wilks formula:

Where:

• \( Total\ Weight\ Lifted \) — Sum of best squat, bench press, and deadlift (kg)
• \( Bodyweight \) — Lifter's body weight in kg
• \( a-f \) — Gender-specific coefficients

Explanation: The formula creates a coefficient that normalizes lifted weight relative to body weight, with different coefficients for men and women.

3. Importance of Wilks Score

Details: The Wilks score allows comparison of strength across weight classes in powerlifting. It's widely used in competitions to determine the "best lifter" award.

4. Using the Calculator

Tips: Enter your body weight in kg, total weight lifted in kg (sum of your best squat, bench press, and deadlift), and select your gender.

5. Frequently Asked Questions (FAQ)

Q1: What is a good Wilks score?
A: 300+ is good for beginners, 400+ is competitive, and elite lifters often score 500+.

Q2: Why are there different coefficients for men and women?
A: The formula accounts for physiological differences in strength relative to body weight between genders.

Q3: Is Wilks still used in competitions?
A: Some federations now use newer formulas like IPF Points, but Wilks remains widely recognized.

Q4: Does Wilks work for extreme body weights?
A: It's less accurate for very light or very heavy lifters outside typical competitive ranges.

Q5: Can I use pounds instead of kg?
A: This calculator uses kg. Convert pounds to kg (1 lb = 0.453592 kg) before entering values.
