This article made me laugh. Is it possible to get a value as low as 1.9% with bioelectrical impedance or poorly trained skin fold measures, yes. Is it accurate..... I doubt it. Maybe 5-6%, but I'd want that verified using dual-energy x-ray absorptiometry (DXA). Often people think that if an athletes looks very lean, he/she doesn't have much body fat. We have body fat under our skin, in the abdomen (visceral adiposity) and in our muscles. Athletes and sports commentators throw these values around, without knowing how amusing these comments are to people that do these measures every day.
