Calculate wilks score. Wilks formula is primarily used in powerlifting contests to identify the best lifter across different weight classes.

🚀 Quick Start

npm i wilks

import { wilks, wilks2020 } from "wilks";

const calculateWilks = wilks({ total: 612.5, bodyweight: 56, gender: "female", unit: "kg" }); // 720.67
const calculateWilks2020 = wilks2020({ total: 612.5, bodyweight: 56, gender: "female", unit: "kg" }); // 847.27

⭐ Usage

The module currently exports "wilks" and "wilks/helpers". You can check the tests to see more examples.

wilks

import { wilks, wilks2020, dots, ipf, ipfgl, oneRepMax } from "wilks";

const input = {
  // Use total
  total: 612.5,
  // Or
  squat: 260,
  bench: 132.5,
  deadlift: 220,
  bodyweight: 56,
  gender: "female" | "male",
  unit: "kg" | "lb",
};

const calculateWilks
  = wilks({ total: 612.5, bodyweight: 56, gender: "female", unit: "kg" }); // 720.67
const calculateWilks2020
  = wilks2020({ squat: 260, bench: 132.5, deadlift: 220, bodyweight: 56, gender: "female", unit: "kg" }); // 847.27
const calculateDots
  = dots({ total: 612.5, bodyweight: 56, gender: "female", unit: "kg" }); // 709.96
// ipf(input, "clpl" | "clbp" | "eqpl" | "eqbp")
const calculateIpf
  = ipf({ total: 1350.4, bodyweight: 123.45, gender: "female", unit: "lb" }, "clpl"); // 1145.88
const calculateIpfGl
  = ipfgl({ total: 612.5, bodyweight: 56, gender: "female", unit: "kg" }, "clpl"); // 145.62
// accepts weight, reps, formula ("brzycki" | "epley" | "lander" | "lombardi" | "oconner") and round to decimal
const calculateOneRepMax = oneRepMax(100, 10, "brzycki", 0); // 133

wilks/helpers

Exports roundToDecimal(input: number, decimal: number): number and convertWeight(weight: number, unit: "kg" | "lb", decimal = 1): number.

import { roundToDecimal, convertWeight } from "wilks/helpers";

console.log(roundToDecimal(123.333, 2)); // 123.33
console.log(convertWeight(163.1, "lb")); // 74
console.log(convertWeight(163.1, "lb", 2)); // 73.98
