How to Calculate Lifting Strength Scores

Lifting strength scores like IPF GL, DOTS, and Wilks are used to compare powerlifters across different weight classes and genders. These scores take into account the lifter's bodyweight, gender, and total lift (sum of squat, bench press, and deadlift) to produce a single number that represents their relative strength.

Lifting Strength Score Formulas

The formulas used in this calculator are:

IPF GL Score:

$$IPF GL Score = 500 + 100 \times \frac{Total - (a \times \ln(BW) - b)}{c \times BW}$$

Where $a$, $b$, and $c$ are gender-specific constants, $BW$ is bodyweight, and $Total$ is the sum of squat, bench press, and deadlift.

DOTS Score:

$$DOTS Score = \frac{Total \times 500}{Coefficient}$$

Where $Coefficient$ is calculated using a 4th degree polynomial based on bodyweight and gender.

Wilks Score:

$$Wilks Score = Total \times \frac{500}{a + bx + cx^2 + dx^3 + ex^4 + fx^5}$$

Where $x$ is the bodyweight and $a$, $b$, $c$, $d$, $e$, and $f$ are gender-specific constants.

Calculation Steps

  1. Input the lifter's bodyweight, gender, and individual lift numbers (squat, bench press, deadlift).
  2. Calculate the total lift by summing squat, bench press, and deadlift.
  3. Apply the chosen formula (IPF GL, DOTS, or Wilks) using the total lift, bodyweight, and gender.
  4. Round the result to obtain the final score.

Example Calculation

Let's calculate the IPF GL score for a male lifter with the following parameters:

  • Bodyweight: 80 kg
  • Squat: 180 kg
  • Bench Press: 120 kg
  • Deadlift: 220 kg

Step 1: Calculate the total lift

$$Total = 180 + 120 + 220 = 520 kg$$

Step 2: Apply the IPF GL formula

For males: $a = 1199.72839$, $b = 1025.18162$, $c = 0.00921$

$$IPF GL Score = 500 + 100 \times \frac{520 - (1199.72839 \times \ln(80) - 1025.18162)}{0.00921 \times 80}$$

$$IPF GL Score \approx 386.23$$

Therefore, the IPF GL score for this lifter is approximately 386.23.
