Ideal Body Weight for Athletes

For athletes, ideal body weight is not just about BMI — it is about achieving optimal body composition (muscle-to-fat ratio) for performance. Different sports demand different body compositions.

Medical Ideal Weight Formulas

Hamwi Formula

Men: 48 kg + 2.7 kg per inch over 5 ft
Women: 45.5 kg + 2.2 kg per inch over 5 ft

BMI-Based Range (Healthy = 18.5–24.9)

Healthy weight range = 18.5 to 24.9 x height (m)2

Lean Body Mass

Lean Body Mass (LBM) = Total weight x (1 - body fat %)

Example: 80 kg person at 15% body fat → LBM = 80 x 0.85 = 68 kg

LBM is the target to preserve when losing weight — only fat should be lost, not muscle.
