Handheld Sensor. With handheld body fat analyzers, you plug in some stats, hold the device out in front of you and hit a button. Within a couple of seconds you’re given a body fat estimate. Here's a list of some popular ones.
Skin Fold Measurements
Most of your body fat is stored directly beneath your skin. Skin fold testing is based around this fact.
You get an accurate estimate of your overall body fat percentage by using calipers to “pinch” folds of skin and fat at several places.
The good: Skin fold testing can be a very accurate way to estimate your body fat percentage. It’s also quick and convenient.
The bad: It takes some practice. The accuracy of the numbers is only as accurate as the person conducting the test. Errors can occur by pinching the wrong spots or using the wrong technique.
You need to repeat all conditions at each test…
The same person should test every time.
The same formula should be used.
The same caliper should be used.
When measuring body fat, it’s not necessary to have laser accurate numbers. You just want consistency in how you test so you can track your results.
When you buy calipers you’ll receive instructions to measure body fat and a body fat percent estimate chart.
