LOL... 10-16% is normal for a woman??
THe average bf% for a female is 25%.
Super girl, what testing method was used on you? Yes, some methods are stricter then others. Depending on the testing method used on you , then you could very easily be at around 30%. The scary thing is a female can actually look really good with 25% bf if she has good muscle shape and is built well with great proportion. Many of the women that are my clients can actually appear "thin". However they usually end up with 25-30% bf when I test them. Here are 2 examples of women I tested last week. first one was age 25, 5'8, 122, she had 32%bf.
Second one was age 25, 5'5 118 25% bf. Their demensions make them appear slim but their body composition is a totally different story.
To answer your question a average bodyfat for a female age 20-25 would be 25%. A average bodyfat for a "athletic" female.. assuming u mean by "athletic" a female with a firm body and noticable definition, this could range from 15-20%. Hope this helps, feel free to email me for any other Q's.
