Wilks Score
Wilks Formula:
Wilks = Total × Coefficient
The coefficient is calculated from body weight using a 5th-degree polynomial:
Coefficient = 500 / (a + bx + cx² + dx³ + ex⁴ + fx⁵)
Where x = body weight in kg.
What makes a good Wilks score?
| Score | Level |
|---|---|
| 200-300 | Beginner |
| 300-400 | Intermediate |
| 400-450 | Advanced |
| 450-500 | Elite |
| 500+ | World class |
The Wilks score is used in powerlifting competitions to compare lifters of different body weights fairly. A 60 kg lifter totaling 400 kg may have a higher Wilks than a 120 kg lifter totaling 600 kg.
