BODY fat percentage? out of whack?!?

i've tried many online calculators and they always say my body fat % is from 18 - 21 at the most. Is this good or bad? im 20, 5'5 and weigh around 123 pounds plus i really don't feel like its that low, though i do run the back of my legs arent very toned.

1. Don't trust an online calculator to give you an accurate bodyfat reading. Have someone who is certified use bodyfat calipers to give you a more accurate percentage.
2. The only accurate way to work out your body fat is to do one of those tests where they suspend you in water or put you in one of those pod things that measure how much air you displace. Even the skin pinch calipers aren't that accurate but I can't even begin to imagine how they work it out online without any of these methods. I wouldn't worry about it. If you feel flabby then tone up, if you're happy with yourself then don't worry about what some silly website says
3. That is a good body fat percentage, but online calculators and scales you buy at stores aren't exactly the most accurate. Next time you go for a check up, ask your doctor if it's possible that he or she may calculate your body fat percentage for you. Anywhere from 15 to 20% is very good. Any other questions, feel free to ask on my blog or through e-mail (blog preferred)! joecapstwatm.blogspot.com E-Mail: aic224@yahoo.com
4. online body fat calculators are a joke. go to a local gym and you can get it checked for $20 or so.
5. "Tanita Body Composition Analyser" available in Gym. gives results of Body Mass Index,BMR,Fat%,Fat Mass,Free Fat mass,and TBW(water). Also determines Target Body Fat,Predicted weight,Predicted Fat mass,and Fat to lose. You just have to stand over the plate and feed the height in meters.
6. my body fat percentage is 0.3 i am 15 weigh 4st 2 am 4ft5in tall severley obese u need to loose urgently and yes online calcs DO work...
7. It's excellent and would be considered between lean and athletic for a female. Although you can't really go by body fat calculators, 18%-21% body fat would be typical of celebs such as Adriana Lima or Jessica Biel. It's where women look very lean without looking overly defined, i.e. bikini body.
