According to ACE's standards, it is normal for female athletes to have between 14 and 20 percent body fat, for fit women to fall between 21 and 24 percent and for average women to have between 25 and 31 percent body fat.
Ideal Body Weight and Percent Body Fat. The ideal weight and fat-lean ratio varies considerably for men and women and by age, but the minimum percent of body fat considered safe for good health is 5 percent for males and 12% for females. The average adult body fat is closer to 15 to 18% for men and 22 to 25% for women. Athletes tend to be at low end of this scale due to their increased lean weight (muscle mass). While low levels of body fat seem to be related to improved performance, body composition alone is not a great predictor of sports success.
