Formulas Used

Strength Ratio

ratio = round(weight_lifted / body_weight * 100) / 100

Distance to 1x BW

to_1x = round(body_weight - weight_lifted)

Distance to 1.5x BW

to_1_5x = round(body_weight * 1.5 - weight_lifted)

Distance to 2x BW

to_2x = round(body_weight * 2 - weight_lifted)

Variables

How It Works

How Strength-to-Bodyweight Ratio Works

Formula

Ratio = Weight Lifted / Body Weight

Common Benchmarks

  • Bench Press: 1x BW is intermediate, 1.5x is advanced, 2x is elite
  • Squat: 1.5x BW is intermediate, 2x is advanced, 2.5x is elite
  • Deadlift: 2x BW is intermediate, 2.5x is advanced, 3x is elite

    • These ratios provide a standardized way to evaluate strength independent of body size.

    Worked Example

    A 175 lb lifter bench presses 225 lbs.

    body_weight = 175weight_lifted = 225
    1. 01Ratio = 225 / 175 = 1.29x bodyweight
    2. 02Distance to 1.5x BW = 175 * 1.5 - 225 = 37.5 lbs more needed
    3. 03Distance to 2x BW = 175 * 2 - 225 = 125 lbs more needed
