Why is a 2x bodyweight squat harder for a 120kg lifter than a 60kg lifter?

Due to the square-cube law: muscle cross-sectional area (which produces force) scales with height squared, while body mass scales with height cubed. Normalization formulas like DOTS or IPF GL correct for this.

Mathematical Formula & Scientific Methodology

Formula: Strength-to-Bodyweight Ratio

Strength Ratio = 1RM Lift Weight / Body Weight

Simple linear strength coefficient measuring relative force production per unit of body mass.

Model Assumptions

Standardized equipment and competition movement standards

Variables & Standard Units

Symbol	Physiological Meaning	Unit
Lift Weight	One rep max lifted	kg/lb
Body Weight	Body mass on date of lift	kg/lb

Scientific Limitations

Due to allometric scaling, heavier athletes face a geometric disadvantage in simple strength-to-weight ratios (use DOTS or Wilks for fairer comparison)
