I finally used a body fat calculator to figure out my body fat. Then I put my goal weight and what I thought were reasonable goal measurements for my waist and hips into the calculator to figure out my goal body fat, and it came out to 18%. This seems really low to me. Is 18% a realistic body fat percentage?? I thought that professional athletes had like 15% body fat.

I know that the goal would differ from person to person, but what would be a reasonable body fat % for a reasonably fit, 40+ year old woman? Anyone?

Thanks,
Jeannie
