1. you obviously did it COMPLETELY wrong. THere is absolutely NO WAY that you can have a negative body percentage. even the healthiest and most fit people in the world have a body fat % of 5-10 percent.
2. Surely not! Sylvester Stallone had body fat of about 4% in Rocky IV and he was just muscle and no fat at all. If it is right, he isn't too healthy so sort it out asap!
3. umm...i dont know if you did it right cause i think you do the height and the weight..cause when i did this in school i dont really think we used waste or maybe we used all three but i kno for sure the height and weight are in the equation.
4. Whether you did it right or wrong, the number is impossible. I'm guessing you used an online body fat calculator as they can give out ridiculous numbers. To get an accurate body fat reading, I'd suggest getting some body fat callipers which you use to pinch a folds of fat on various parts of the body.
