Enter Sex, Bodyweight (kg), Total lifted (kg) and the Wilks Calculator works out Wilks score straight away. For instance, with Sex = Male, Bodyweight (kg) = 80 and Total lifted (kg) = 400 it returns Wilks score = 273.079.

How to use it

  1. Enter your values: Sex, Bodyweight (kg), Total lifted (kg).
  2. Read the result instantly: Wilks score.

Frequently asked questions

What does the Wilks Calculator actually compute?

It takes Sex, Bodyweight (kg) and Total lifted (kg) and derives Wilks score from them. The calculation is live as you type, so the result updates on every change.

What information do I need to provide?

3 values: Sex, Bodyweight (kg) and Total lifted (kg). Nothing else is required — no account, no file upload.

Can you show a worked example?

With Sex = Male, Bodyweight (kg) = 80 and Total lifted (kg) = 400, the calculator returns Wilks score = 273.079. Those figures come from running this exact tool, so you can reproduce them by entering the same values.

What happens if I enter larger values?

It moves a lot. Using Sex = Female, Bodyweight (kg) = 88 and Total lifted (kg) = 440 instead, Wilks score goes from 273.079 to 383.867 — which is why it is worth testing a few scenarios rather than trusting a single figure.

Which “Sex” option should I choose?

You can pick between « Male » and « Female ». Each one changes what the calculator works out, so switch and compare — the default is « Male ».

What does it give for smaller values?

Scaled down to Sex = Male, Bodyweight (kg) = 72 and Total lifted (kg) = 360, Wilks score comes out at 264.135. The relationship is worth checking at both ends before you rely on a single result.

When would I actually use this?

Programming a block: estimating a one-rep max without testing it, setting working loads as a percentage of it, and tracking whether volume is actually going up.

What is the most common mistake?

Estimating a one-rep max from a high-repetition set. The formulas hold to about five reps; beyond ten they drift badly, because endurance starts to dominate strength.

Where do the figures come from, and how current are they?

The estimates use the published Epley and Brzycki equations, which the tool names. They were derived on trained lifters and describe a population, not your best day.
