Precentage Muscle In The Body I Did An Online Body Fat Percentage Test...help?

I did an online body fat percentage test...help? - precentage muscle in the body

She says that my body fat percentage of 31%, but I'm tiny! People tell me I'm thin all the time. I weigh over 118 pounds, and I'm 5'6''. They told me that my waist measurement of weight, waist, hips-24-35-6 wrists, thighs make (which is great) - 24 and Calf-12. I suspect that because my legs are very muscular. I walk or bike for an hour or more per day, as I prepare for cross-country trail this fall. Too many skis in the winter, and have a lot of leg exercises such as squats, lunges, leg lifts, so that all summer, done. Is it possible that the page does not take into account properly and that could have more muscles? My legs looked really not big at all ithere. Not like a madman, raw and muscular, but you can tell when flex I think the reason my legs do not look fat, because they are very long (like 34''inseem). There are basically no fat or wrist, and my hips and waist are so great, because (in my ribs and pelvic bones and I can not help me!) On Denil, I am large, or was in the wrong place? In addition, my BMI is only 19 I am not looking for compliments and really do not want to answer, please! Tell me if there is another way to explore my body fat at or if I'm fat. Thank you!
