Ideal Weight for Athletes and Lifters
Athlete ideal weight — FFMI and body fat over formulas.
Standard ideal weight formulas assume average body composition. Athletes with significant muscle mass will exceed these ranges while being healthier than the formula suggests.
Why formulas underestimate athlete weight
Devine and Robinson were derived from insurance data for average adults. A male lifter at 185 cm and 90 kg with 12% body fat is lean but reads 'overweight' on every formula.
Use FFMI instead
Fat-Free Mass Index accounts for height and body fat: FFMI = lean mass (kg) / height (m)². Men above 25 and women above 21 typically indicate above-average muscularity.
Sport-specific targets
Endurance athletes often sit at the lower end of healthy BMI. Strength athletes prioritize performance metrics over scale weight. Weight-class athletes target composition, not formula output.
When ideal weight formulas help athletes
During off-season if body fat has crept above 20% (men) or 28% (women), formulas provide a rough re-entry range. Pair with body fat measurement for accuracy.
