BMI Limitations

Standard BMI cannot distinguish muscle from fat. Athletes with high muscle mass may show "overweight" or "obese" BMI while being very healthy. This calculator provides muscle-adjusted analysis.

🎯 FFMI (Fat-Free Mass Index)

Formula: FFMI = Fat-free mass(kg) / Height(m)²

Male Average: 18-20

Female Average: 15-17

What is BMI?

BMI (Body Mass Index) is a measure that uses your height and weight to assess your health status. It is calculated by dividing your weight in kilograms by your height in meters squared.

BMI Formula

BMI = weight(kg) ÷ height(m)²

BMI = weight(kg) ÷ height(m)². For example, a person weighing 70kg and 175cm tall has a BMI of 70 ÷ 1.75² = 22.9.

Healthy Weight Management Tips

  • ✓BMI is just a reference indicator; it doesn't account for muscle mass or body fat percentage
  • ✓Regular exercise and a balanced diet are important
  • ✓Rapid weight changes can be harmful to your health
  • ✓Consult a healthcare professional for accurate health assessment

💡 Tips for Athletes

  • Don't judge health by BMI alone
  • Measure body fat % and FFMI together
  • Regular body composition tests (3-6 months)
  • Set different goals for on/off season
  • Maintain extreme low body fat only short-term

❓ FAQ

Is BMI of 30 obese for athletes?

Not necessarily. Athletes with high muscle mass can be healthy at BMI 30+ if body fat is low. Check body fat % and FFMI together.

Is FFMI above 25 impossible naturally?

FFMI 25 is known as the approximate natural limit. A few with genetic advantages may exceed it, but most above 25 suggests drug use.

How do I measure body fat percentage?

Options include bioelectric impedance (InBody), skinfold calipers, hydrostatic weighing, and DEXA scans. Use a consistent method for regular tracking.

⚠️ Extreme low body fat (below 5% for men, 12% for women) is harmful. Contest conditioning should be short-term under professional guidance.
