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.
Since increased body fat percentages automatically yield lower water weight percentages, the highest water weight levels, 58 to 70 percent, are assigned to women with 4 to 20 percent body fat, and the lowest, 37 to 49 percent, are assigned to women 33 percent fat and above.
