BMI Calculator for Athletes
Calculate BMI with sport-specific context (BMI is often misleading for athletes)
Why BMI Doesn't Work for Athletes
BMI doesn't distinguish between muscle and fat. Many professional athletes have "overweight" or "obese" BMI despite being in peak physical condition.
Better Metrics for Athletes
- Body Fat Percentage: 10-15% for male athletes, 18-25% for female athletes
- Fat-Free Mass Index (FFMI): Better for muscular individuals
- Waist-to-Hip Ratio: Health indicator independent of muscle mass
Typical BMI by Sport
- Marathon Runners: 18-22 (lean and light)
- Swimmers: 21-24 (lean muscle)
- Bodybuilders: 25-30+ (high muscle mass)
- Football Linemen: 30+ (size advantage)
