1. What is the Wilks Score?

The Wilks score (or Wilks coefficient) is a coefficient used to compare the strength of powerlifters while accounting for differences in body weight and gender. It allows for fair comparison between lifters of different sizes.

2. How Does the Calculator Work?

The calculator uses the Wilks formula:

Where:

• \( bench \) — Bench press weight in kg
• \( coeff \) — Wilks coefficient based on body weight and gender

Explanation: The Wilks coefficient is calculated using a polynomial equation that differs for males and females, taking into account the lifter's body weight.

3. Importance of Wilks Score

Details: The Wilks score is important in powerlifting competitions to compare performances across different weight classes. It helps determine the most impressive lift relative to body size.

4. Using the Calculator

Tips: Enter your bench press weight in kg, select your gender, and enter your body weight in kg. All values must be valid (weight > 0).

5. Frequently Asked Questions (FAQ)

Q1: Why use Wilks score?
A: Wilks score allows for fair comparison of strength between lifters of different body weights and genders.

Q2: What is a good Wilks score?
A: A Wilks score of 300+ is considered good, 400+ is excellent, and 500+ is world-class.

Q3: Does this work for machine bench press?
A: Yes, though Wilks is typically used for free weight lifts, it can be applied to machine lifts for comparison.

Q4: Are there limitations to Wilks?
A: Wilks may not be as accurate for extreme body weights and newer formulas like IPF points may be more precise.

Q5: Should I use kg or pounds?
A: The calculator uses kg. Convert pounds to kg by dividing by 2.205.
