A personal trainer at the health club today was measuring people's body fat and told me that although I'm a thin person, I have too much fat. She pinched the flesh on my waist, under arm and thigh and measured it with a caliper and then compared that to a chart for women my age. She pinched my thigh sooooo hard that I swore out loud and have a huge bruise.
She said that sometimes it's hard to grab the adipose fat on your thighs. But damn, it still hurts, 7 hours later!

Has anyone ever had this test? Is it possible she did something wrong? I'm not saying I'm in tiptop shape, and especially my arms are flabby.
