§03Practical Example

Step-by-step walkthrough

Scenario

Apply the formula to a realistic set of inputs: Bodyweight (kg) = 80, Total lifted (kg) = 500.

  1. 01Start by noting the input — Bodyweight (kg): 80.
  2. 02Start by noting the input — Total lifted (kg): 500.
  3. 03Substitute these values into the formula: 500 × e.lifted / (16.2606339 × t-216.0475144-.002388645 × t²)
  4. 04Compute Wilks: the calculator returns 233.751.
  5. 05Cross-check the answer by opening the Derivation panel above — every line of math is shown so you can follow the computation end-to-end.

Common Wilks Coefficient Problems

The formula gets rearranged depending on which variable you need. Here are the patterns you’ll run into in the real world — find the one that matches your problem and follow the worked steps.

01 · PATTERN

Bodyweight (kg) halved

bw = 40 (from 80)

Keep every other input at its default and halve the bodyweight (kg). See how wilks responds.

  1. 01New Bodyweight (kg): 40
  2. 02Baseline Wilks: 233.751
  3. 03New Wilks: 580.645
  4. 04Wilks increases by 148.4% → use this sensitivity to plan for real-world variation.
02 · PATTERN

Bodyweight (kg) doubled

bw = 160 (from 80)

Keep every other input at its default and double the bodyweight (kg). See how wilks responds.

  1. 01New Bodyweight (kg): 160
  2. 02Baseline Wilks: 233.751
  3. 03New Wilks: 107.55
  4. 04Wilks decreases by 54% → use this sensitivity to plan for real-world variation.
03 · PATTERN

Total lifted (kg) halved

lifted = 250 (from 500)

Keep every other input at its default and halve the total lifted (kg). See how wilks responds.

  1. 01New Total lifted (kg): 250
  2. 02Baseline Wilks: 233.751
  3. 03New Wilks: 116.875
  4. 04Wilks decreases by 50% → use this sensitivity to plan for real-world variation.
04 · PATTERN

Total lifted (kg) doubled

lifted = 1000 (from 500)

Keep every other input at its default and double the total lifted (kg). See how wilks responds.

  1. 01New Total lifted (kg): 1000
  2. 02Baseline Wilks: 233.751
  3. 03New Wilks: 467.501
  4. 04Wilks increases by 100% → use this sensitivity to plan for real-world variation.
