What 12% Body Fat Looks Like
Bottom of essential fat. Very lean with visible muscle definition. Defined abs, toned arms. Athletic but at the edge of health for most women.
Female bodybuilders and figure competitors like Andreia Brazier and Dana Linn Bailey have been measured in the 10-13% range on competition day. These levels are maintained for hours and cause menstrual disruption.
